Devices fabricated on 4 µm thick SOI wafers are presented. They include a router based on AWGs and SOAs, a demultiplexer based on cascaded MZIs, ring resonators, and a novel concept of MMI resonator.
Photonic Networks-on-Chip (NoC) is considered as a promising candidate to interconnect a large number of processing cores. The heart of a photonic NoC is the on chip photonic interconnection network which is composed of silicon waveguides and optical routers. In this paper, we propose a scalable and non-blocking passive optical router design using micro-ring resonators (MRRs), namely the generic wavelength-routed...
This paper presents the design of laterally coupled racetrack microring resonators working around 1.55μm, using combinations of the 3D full vectorial film mode matching method, the coupled mode theory and the parameter model. This combined simulation technique shows convenience to perform the design process.
This paper presents an overview of our work on the theory, design, fabrication, and integration of micro/nano-scale optical devices as applicable for all-optical generic and application-specific VLSI photonic integration. The micro/nano-optical devices are designed to perform the functions of collecting, storing, transporting, processing, switching, routing, and distributing optical signals on chips...
A silicon photonic-wire waveguide based wavelength tunable laser was firstly demonstrated; whose micro-ring resonator footprint was 700 times 450 mum. Its wavelength tuning range is 38 nm at a tuning power of 26-mW.
We demonstrate GHz-speed electro-optic modulation using microring resonators in a deposited layer of polycrystalline silicon. Active optical devices in a deposited microelectronic material can enable monolithic large-scale integration of photonic networks on a microelectronic chip.
We demonstrate critically coupled silicon microring resonators with intrinsic Q close to 300,000 and mode volume Vap20times(lambda/ne)3. For sub-mW optical power, large pump induced resonance shifts were observed for applications in all-optical switching.
Analytical models for bandwidth and bandwidth-efficiency product (BEP) of microring waveguide photodetectors (MRWPDs) are presented. In addition to carrier transport and charging processes, the photon lifetime effect is included in the bandwidth model. This effect is characterized by the ODB of microring resonators. It is shown that the short cavities and partially overcoupled structures are suitable...
A modulator design based upon anti-crossing between coupled silicon microrings with independent amplitude-phase functionality, is presented. The device has a footprint of 0.003 mm , exhibits over 10times improvement in modulation sensitivity, and 14 dB extinction.
We design a silicon MMI crossing laterally coupled microring resonator-based cross-connect filter. Numerical simulations suggest our design exhibits reduced insertion loss, reduced crosstalk, and more symmetric Lorentzian lineshapes as compared with the conventional plain-crossing-microring design.
