Residential multi-service access networks and photonic computing
FY 2008-09
Summary
My current research is subdivided into two major programs: Program-1: Broadband Residential Integrated Services Networks, and Program-2: N-nary Digital Photonic Computing. The objective of program-1 is to develop the technologies for broadband residential integrated services networks. With the advancement of the DWDM (Dense Wavelength Division Multiplexing) technology, it becomes sensible now to combine existing network protocols, namely the Ethernet or the SONET, with DWDM to achieve a new generation of metro networks for broadband multi-service to homes. In this Program, we are currently researching, in parallel; two access network models, one is based on the SONET and the other is based on the Ethernet. The goal is to compare the two architectures in order to develop an efficient and low cost network system for future broadband residential communication services. We have designed the architectures and developed the access protocols for both network models. Our current focus is on developing a low cost residential gateway (RG) for each of our network systems. Program-2 is based on my inventions of Photonic Semiconductor Transistors (PST) and N-nary Digital Photonic (NDP) System (US patent #67783030) and Optical Memories (US patent #6647163). Similar to electronic semiconductor transistors, photonic semiconductor transistors are the fundamental elements for digital photonic circuits. The PSTs are used to construct logic gates and then logic gates are used to build digital photonic devices, in the same manner as digital electronics. The NDP system uses N (N>=2) number of wavelengths to encode information, which leads to high memory capacity and computing speed. An N-valued digital logic system has been developed which enables circuit designs by using the N-nary photonic logic gates (US patent #67783030). We are currently using the Optiwave software to design the microstructure of PSTs. The design has been submitted to NRC Canadian Photonics Fabrication Centre (CPFC) for prototyping.
