Optical signal processing by means of photonic engineering has proven to be essential in modern high-speed information and communication systems and networks. Some impressive functionalities beyond simple filtering include: arbitrary waveform generation, Tb/s transmission, optical FFT/IFFTs, THz-bandwidth signal processing, comb-based photonic RF filters, and photonic beamformers for phased array antennas. In the field of optical communications, some basic techniques such as optical filters, switches, (de)multiplexers, amplifiers, dispersion compensators, and the like, have enabled us to share data over long distances at Gb/s rates. Promising nonlinear optical techniques may allow for more powerful processing functionalities, such as: wavelength conversion, optical logic, time lenses, parametric gain, and all-optical regeneration; all of which could play a significant role in future optical communication systems and networks. From the industrial perspective, however, the deployment and proliferation of optical signal processing depends strongly on the advance of photonic integration technology, which is the most effective way to simultaneously address the concerns of: fabrication cost, footprint, energy consumption and performance, as is evident from the experience of the electronic integration. The ability to realize integrated photonic signal processors on the chip scale is therefore the key for optical signal processing in the future. This talk will cover three main points: (1) why do we do photonic engineering on the chip scale? (2) what are the promising application areas?; (3) what are we expecting for the future on this study?

Leimeng Zhuang received his BSc degree in telecommunication engineering from the University of Electronic Science and Technology of China (UESTC), Chengdu, and received his MSc (with honor) and PhD degrees in electrical engineering from University of Twente, the Netherlands. In the period from 2009 to 2014, he worked as a research fellow and project coordinator at University of Twente, XiO Photonics B.V., SATRAX B.V. (currently LioniX International), and Netherlands Aerospace Laboratory (NLR), responsible for the development of an electrically-steered Ku-band satellite tracking phased array antenna system using an integrated photonic beamformer. In the meantime, he was also in collaboration with LioniX International developing integrated optical signal processors for RF applications. From 2014 till now, he has been working as a senior research fellow with Electro-Photonics Laboratory at Monash University, Australia, leading the research activities on electrical and optical signal processing and photonic integrated circuit design for the establishment of a hybrid electronics-photonics technology platform serving for high-speed, energy-efficient optical communication and microwave photonic systems.
