Title: Silicon Photonics for Current and   Future Applications in Information Technology

Abstract:

The   relentless push toward the Moore’s law limits by integrated circuit (IC)   industry produces excellent nano-scale silicon fabrication processes that   pave a bright future for the silicon photonics technology. The current   silicon photonics platform is based on SOI waveguides which exhibit a large   index contrast between core (Si) and cladding (SiOx) materials. It leads to a   strong mode confinement in Si waveguide that yields highly dense planar   lightwave circuits. Silicon photonics possesses the unique advantages of:   CMOS compatibility for low cost high yield production; integrate-able to VLSI   circuits for control and functionality intelligence; and a full arsenal of   passive and active components for communications, networking, signal   processing and sensor operations. Applications of information technology   based on silicon photonics includes broad band interconnects that take   advantage of optical communication channels for both short and long hauls.;   Integrated signal processing solutions of optical communication signals that   utilize the polarization, phase and wavelength characteristics of photons;   Highly integrated optoelectronic circuits for various sensor applications;   Integrated optoelectronic circuits with intelligent electronic circuits for   current and future information technological applications.

In this tutorial talk, we will briefly review the evolution and   development of silicon photonics technology and highlight a few exciting   current and future applications.  One   of the most important up-and coming technology areas is Internet of Things   (IoT) that combines smart sensors, broad band communications, and big data   analysis.  Silicon photonics technology   is uniquely positioned as the enabling technology platform.

Title: Transmission Techniques for Inter   and Intra Data Centre Systems

Abstract:   The proliferation   of optical transmission technology in high capacity data centre systems has   driven the research study on techniques that can enable low cost, low energy   consumption transmission over short distance. The focus has been on direct   detected systems due to cost and energy concerns. High order modulation   schemes with direct detection has been investigated since the bandwidth of   optical components utilized in such systems is typically much lower than   desired data rate. Here we describe the study we have carried out on a number   of modulation schemes and corresponding digital signal processing employed to   optimize system capacity. The focus will be on direct detected polarization   multiplexing schemes. Theoretical study and experimental demonstration will   be highlighted. Some of the key challenges and future perspectives will be   discussed.

Title: Artificial photosynthesis of glucose   using solar photocatalysis

Abstract: Solar energy is the fundamental   energy source of human being. Recent years have witnessed a rapid increase of   research interest in the photocatalysis technology that focuses on the   conversion of solar energy into chemical energy, such as the degradation of   organic pollutant, the splitting of water into hydrogen and the capture of   CO2 into energy-rich carbohydrates. However, the current photocatalysis   technology has the fundamental problems such as mass transfer limit, photon   transfer limit, electron/hole recombination, oxygen deficiency/removal and   many others. To overcome these problems, our group has explored the   microfluidics technology and has found that it can significantly improve the   efficiency of photodegradation of organics. Recently, we have attempted to   generate glucose using CO2 and sunlight by replicating the photosynthetic   processes in a microfluidic chip, and have successfully realized the   functions of NADPH regeneration, glucose conversion and deoxygenation. This   work may lead to a new route to producing basic food materials like sugar and   starch using factory-like production lines.
