报告题目及内容：Integrated Photonic Systems and Optical Networking Technologies in Future Computing and Communications
This talk will cover advanced optical networking architectures, systems, and device technologies for that will significantly impact the performance and energy-efficiency of future computing and communications systems. We will provide several key examples. In the first example, we will introduce a new class of optical switching system designed for interconnecting computing systems in data centers. The optical switching system exploits rapidly tunable wavelength converters and uniform-loss-cyclic-frequency arrayed-waveguide grating routers with a pipelined arbiter. The switching fabric is contention-free and scalable beyond 2 milion port x 2 million port and 42 petabit/second aggregate switching capacity in a single stage switch with less than 50 ns latency. The second example shows > 1 Terabit/second transmitter and receiver using coherent optical signal modulation and detection. Arbitrary and advanced deta format modulation with spectral efficiency at 3 bit/s-Hz and 1.2 Tb/s data rates have been demonstrated. The third example shows energy-efficient photonic signal processing and interconnects enabled on CMOS-compatible silicon-on-insulator photonic integrated circuits. We will discuss recently developed silicon CMOS-photonic integrated circuits capable of reconfigurable signal processing. The talk will conclude by addressing the future prospects on photonic-electronic-integrated circuits and their impacts on future ICT.
