    Silicon photonic devices for signal processing in wavelength, polarization and mode
    Abstract:

    We experimentally demonstrate optical filtering, polarization splitting and rotating, and mode (de)multiplexing and switching in silicon devices.
    We firstly demonstrate silicon photonic filters based on Sagnac loop reflectors, including a wavelength and bandwidth-tunable comb filter, and two compact interleavers in the Michaelson interferometer and interfering loop configurations with compact footprints.
    We then discuss a high extinction-ratio (30 dB) silicon polarization beam splitter (PBS) based on a grating-assisted contra-directional coupler (GACC), and an ultra-compact silicon polarization splitter and rotator (PSR) with a short coupling length of 8.77 micron.
    We further talk about optical switching in wavelength, mode, and polarization. We demonstrate a 2x2 nanobeam thermal-optic switch with ultra-small mode volumes, a high tuning efficiency of 1.23 nm/mW and an ultra-low switching power of 0.16 mW. We then propose a mode- and polarization-selective switch (MPSS) architecture for next generation high capacity switching systems, and demonstrate 1x2 and 2x2 on-chip MPSS switches.

    Title: Nonlinear Silicon Photonics
    Abstract:
    Nonlinear optics was born immediately after the first laser was demonstrated. As an important branch of optics, nonlinear photonics is at the heart of frequency conversion, amplification, soliton and pulse compression, supercontinuum generation, and laser mode-locking and frequency comb generation, which have found a wide variety of applications in optical signal processing, communications, sensing, imaging, and metrology.Several fundamental advantages drive nonlinear silicon photonics, including (i) as bulk material, crystalline silicon typically has stronger Kerr and Raman nonlinearities than silica by 2~3 orders of magnitude; (ii) the high index contrast in silicon photonics not only allows sub-wavelength light confinement but also makes it possible to form novel waveguiding structures; (iii) CMOS compatibility in silicon device processing and fabrication can be utilized for nonlinear silicon photonics; and (iv) cost-effectiveness and portability of devices enabled by silicon photonics can be directly transferred to the nonlinear optics branch. In this lecture, we present basics of nonlinear silicon photonics and review research works on various types of silicon and germanium waveguides for broadband nonlinear applications. We discuss the material properties of silicon, silicon nitride, silicon nano-crystals, silica, and germanium. Various devices are analyzed for spectrum ranges from visible, near-IR to mid-IR.

    Title: Fabrication and Packagingof Silicon Photonics -things to be considered in chip design
    Abstract:

    Silicon photonics is currently at the same early stage of development as microelectronics was in the 1970s. The designers must own some basic understanding of fabrication and packagingat the very beginning of scheme.The most attractive aspects of photonics on silicon arethe low primary cost of the material, the mature processing techniques, andthe potential for straightforward integration with electrical componentsin the same substrate. Even silicon photonics is always claimed to be CMOS compatible, every attempt to directly integratephotonic functionality into the advanced CMOSline so far, without making anyprocess changes, has yielded poorly-performing devices or economic waste. Some special technologies (e.g. Ge on Si) are important in silicon photonics devices. Also, the large refractive index contrast of silicon photonics makes the coupling between silicon waveguide and outside world, for example single-mode fiber and semiconductor laser chip, a challenging work.In this course,thestate-of-the-art fabrication and packaging technologies and design rules of silicon photonics are introduced.

    微光刻、电子束光刻光刻及标准化技术
    Abstract:
    Currently Intel is leading IC production to 10 nm node while SMIC is in 28 nm and developing the process for 7-10 nm IC production. Representing with demonstration on 10 nm circuits and devices, research institutes and universities in China are working on process technology of nanometer CMOS, including sub-20 nm IC technology. EBL is the absolute lithography process step for 22 nm or below IC technology as EUVL (Extreme Ultraviolet Lithography ) and MEBL (Multiple Electron Beam Lithography)are not available currently in China. With very high resolution EBL is dominated in nanometer IC research while its low writing speed prohibits its application in IC production. Mix & Match is one of the solution to combine the high efficiency of optical lithography and high resolution of EBL, that is patterns of nanometer structures is written with EBL while other patterns is written with optical lithography. There are some issues in EBL applications, e.g. proximity effect caused by scattering and back scattering; charging caused by insulator or dielectric film; drifting caused by electron beam column, developing process, magnetic field and temperature of environment, voltage variation; collapse of structures with high-aspect-ratio in nanometer scale, and developing high resolution resist with high contrast,? etc. In China there are two committees regarding micro-lithography standization, one is Technical Sub-Committee of Micro-Lithography of National Standardization Technology Committee for Semiconductor Equipments and Materials, another is Micro-Nano-fabrication Group of Standardization Technology Committee for Nanometer Sciences. Both organizations are working on applying international standards of micro-lithography to IC industry and research field in China.

    Abstract:
    High temperature stability and high feedback-noise tolerance of the quantum dot lasers are advantageous features for silicon photonics.

In addition, we report the first demonstration of a hybrid silicon quantum dot laser, evanescently coupled to a silicon waveguide. InAs/GaAs quantum laser structures are transferred, by means of direct wafer bonding, onto silicon waveguides defining cavities with adiabatic taper structures and distributed Bragg reflectors. Continuous-wave operation has been realized at 25 °C. Distributed Feedback Finally, we show lasing operation in an InAs/GaAs quantum dot laser directly grown on Si on-axis (100) substrate by the molecular beam epitaxy (MBE).

    Title 1: Silicon On-chip (De)multiplexing Devices:Principles, Structures and Applications (1)
    Title 2:Silicon On-chip (De)multiplexing Devices:Principles, Structures and Applications (2)

    Abstract:

    In order to enhance the capacity of an optical-interconnect link, a cost-effective approach is utilizing advanced multiplexing technologies, e.g., wavelength-division-multiplexing (WDM), polarization-division multiplexing (PDM), spatial-division multiplexing (SDM), etc. The WDM technology has been developed successfully to enable tens of channels within the transparent window around 1550nm to transmit along a singlemode optical fiber/waveguide for optical communication networks. PDM has also been used for enhancing the capacity for long-haul optical fiber communications by utilizing two orthogonal polarizations together with phase modulation or optical QAM. And PDM is generally used in conjunction with advanced channel coding techniques, allowing the use of digital signal processing to decode the signal. In contrast, it is not necessary to working with advanced channel coding techniques as well as digital signal processing,which makes the PDM simplified greatly. Another effective way to improve the link capacity is using the so-called “spatial-division multiplexing (SDM)”, i.e., with multi-core or multimode optical waveguides/fibers, which have attracted intensive attention for long-haul optical fiber communications in the past decades. In this way, the independent signals are carried by different cores or modes in parallel. Finally these multiplexing technologies can work together to form a kind of multi-dimensional hybrid multiplexing technology.
    In order to realize these multiplexing technologies, (de)multiplexers are definitely necessary as the key component. Since silicon photonics has provided a very attractive platform to build ultrasmall integrated photonic devices with a standard CMOS processes, in this lecture we focus on the discussion of silicon-based (de)multiplexers, including WDM devices (arrayed waveguide grating, optical micro-cavities), PDM devices (polarization beam splitters, polarization rotators), mode (de)multiplexers, as well as the devices for the multi-dimensional hybrid multiplexing technology. The principles and the recent progresses of all these silicon on-chip (de)multiplexers are introduced.

    Title:Silicon Photonics for Life
    Abstract:
    Electronics that are based on Si materials have changed human life significantly.Therefore,it is expected that Si-based photonics will further change our life. In this talk, we will address three aspects that Si-photonics can give potential applications. They are optical communication, chemical detection, and solar cells. Nowadays, data network is becoming complex and large. However, copper, as a conventional interconnecting material, is limited due to issues of power consumption, crosstalk, fundamental speed, and bandwidth. In addition, interconnect using electronic methods wastes large power at high frequency. These main disadvantages and all other reasons motivate optical interconnect, which features low power consumption and high bandwidth density. Si-photonics is an excellent candidate for optical interconnect. Mature CMOS fabrication technology enables low cost and massive production of Si-photonics. Nevertheless, most of the silicon photonic devices are fabricated on silicon-on-insulator (SOI) wafer, which limits its development to integrate with electronic devices for being mainly made on bulk silicon substrate. Therefore, fabricating Si-photonic devices on bulk silicon substrate becomes a major mission for realizing optical interconnect.Here we demonstrate that cylindrical silicon optical waveguide can be fabricated on bulk (100) silicon substrate by applying excimer laser treatment. We also explore theSi-basedspectrometer. Here two possible ways are under development. One is curved grating using Si fabrication techniques, combined with Si-based IR detectors. The other is composed of waveguides and a series of high-Q resonators with different sizes. Light can be coupled into and propagate through the waveguides. Then various wavelength components are resonating in different resonators for spectral detection of chemicals. For solar cells, Si is also the most popular materials. Nonetheless, the conventional Si-based solar cells needs high vacuum and high temperature processing procedures. In addition, the efficiency is limited to 30% in theory. I will discuss the possible ways to simplify fabrication process and new approaches to exceed the 30% efficiency limitation.

    Title: III-V Lasers on Silicon for Silicon Photonics
    Abstract:
    The available of silicon lasers is the key technology for the whole Si photonics industry. But the indirect bandgap of silicon is a severe limitation, and, despite recent advances, these devices will not, in the foreseeable future, outperform their III-V counterparts. Much effort has been directed toward hybrid integration of III-V lasers with Si photonics platforms. Although impressive results have been achieved, on a longer term, large-scale integration of photonics circuits will rely on monolithic integration of laser sources on silicon.

    In this lecture, we first review recent progress, through several approaches,in III-V lasers on silicon,in particularly, in the direct epitaxial growth of III-V lasers on Group IV substrates. The basic design rules of monolithic growth of III-Vs on group IV materials will be introduced. We then describe more details in terms of new growth techniques developed for the formation of high-quality III-V buffer layers grown directly on Ge, Si and Ge/Si substrates by Molecular Beam Epitaxy (MBE). Device fabrication and characterization for group IV based III-V lasers will also be discussed.
