Report title:Silicon nanophotonics for Bio-Sensing, Interconnects and Computing Applications

Summary of the report:

      Silicon-based integrated circuits have been an indispensable element for our civilization. In our daily life, everyone carries billions of silicon-based transistors. Such things as IPhone, laptops, memory sticks and data centers are the most prominent parts of our daily work. With the saturation of Moore's law, the silicon-based nanotechnology must solve key issues such as power consumption, latency, and total bandwidth limitations to find feasible solutions. At this seminar, I will use silicon integrated photonics to solve the problem of interconnection and computing performance and propose a viable solution. At the same time, I will also introduce the further applications of silicon photonic devices in biological, chemical and environmental sensing. Different form nanoelectronics, the interconnection loss of optical interconnect is unconcerned with bandwidth. In addition, Bosons (photons) is different from fermions (electrons) which need to comply with the Pauli Exclusion Principle. Ultra-dense photons can coexist in the same quantum space. A variety of Nano-devices can be fully realized in the field of photonics, such as dwdms, optical waveguide intersections, interleavers, etc.

      Another very promising silicon photon nanotechnology is biologically and chemically sensing. Using on-chip slow-light silicon photonic chips, we have demonstrated early breast cancer, lung cancer, pancreatic cancer testing, drug screening, water and air pollution testing They can be widely used in the research on environmental monitoring and environmental health and fill the lack of analytical technology in these field. We are developing an unprecedented sensitive handheld system without damaging the specificity. We have received more than 20 patented intellectual property portfolios from the Omega Optical Research Team (www.omegaoptics.com) and the University of Austin (www.mrc.utexas.edu/people/faculty/ray-chen) and have prepared further business plan.
