Seminar – Photonic Integrated Circuits & Systems
On November 20, a the technical seminar on Photonic Integrated Circuits & Systems from cutting-edge research to industry applications is given at NTU. The two speakers are Ton Backx, CEO Photon Delta and Wang Hong, Associate Professor in the school of EEE at NTU. The seminar is jointly organized by LUX photonics consortium, The Photonics Institute and Holland Innovation Network.
Prof.dr. Ton Backx: Photonic Integration: The basis for the next industrial revolution
Solid state microelectronics have had a major impact on societal evolution over the past 50 years. However, with the development of laser technology and photonic integration technologies, a key enabling technology is at the start of the next societal revolution. Photonic Integrated Circuits (PICs) and Integrated Photonic-Electronic Systems enable the development of low cost systems that can process massive amounts of data, at low energy demand per processed bit and at very high data rates. Primary applications include data processing in data centres, as well as 5G telecommunications – to handle the rapid growth of data traffic and reduce the energy required for processing. Other applications consist of accurate distance and displacement measurement, LIDAR systems (autonomous driving), OCT sensor systems and extremely accurate and fast spectroscopy; which can be applied to many areas, e.g. biomedical, chemical processing, agriculture, air quality analysis. Photonic Integration will certainly be a keystone in solving the major challenges that we are facing today – global warming, transition to sustainable energy, air and water pollution, global food supply and healthy aging.
Prof.dr.ir. Ton Backx is the initiator and president of Photon Delta – an eco-system for companies and R&D institutes involved in photonic materials, photonic integrated circuits and photonic systems. He is also president of the Institute for Photonic Integration at the Eindhoven University of Technology (TU/e). Much of Ton’s career has revolved around TU/e, where he completed his MSc degree in Electrical Engineering (Cum Laude) and PhD on contributions to the identification based modelling of MIMO industrial processes, in 1977 and 1987 respectively. A specialist in the field of applied research on model based process control, model reduction and process optimisation, Ton was appointed part-time professor in the Control Systems group in 1990, before joining the university full-time as Dean of the Department of Electrical Engineering from 2006 – 2016. For the past two decades, Ton has also held senior management positions within Setpoint and AspenTech, and founded companies IPCOS and InSolutions, which specialise in high performance model predictive control and process optimisation. His other involvements include working as principal consultant for Hydrocarbon, Chemical and Glass Processing Industries, as well as initiating and supervising many national and major European R&D projects on process modelling and process performance improvement.
Prof Wang Hong: Development of Silicon Photonic Devices for Mid-Infrared Applications
Silicon Photonics is one of the most buoyant technologies in the world today, set to revolutionise short reach interconnects for applications in computing & communications; as well as impact sensors, domestic appliances and healthcare in the longer term. In recent years, group IV (Si and Ge) photonics research has focused on telecom 1.3 and 1.55 µm wavelengths. Here, we report the development of Si-photonic devices covering the mid-infrared (MIR) wavelength range, which can be used for both communication and sensor applications. Both Si and Ge platforms were investigated due to their good transparency (Si: 1.1 to 8 µm; Ge: 1.9 to 15 µm), high nonlinear coefficients, refractive indices and modulation effects in the MIR. Different Si-photonic devices working at 2 µm and 3.8 µm were designed, fabricated and characterised. The results will be discussed in this talk.
Prof Wang Hong is an Associate Professor in the School of EEE, Nanyang Technological University (NTU). He is also Director of Nanyang NanoFabrication Centre (N2FC) and Deputy Director of Silicon Technologies – Centre of Excellence (Si-COE). Dr Wang received his B.Eng. degree from Zhejiang University, China, in 1988; M.Eng. and Ph.D. degrees from NTU in 1998 and 2001 respectively. Before joining NTU in 1996, he worked at the Institute of Semiconductors, Chinese Academy of Sciences, followed by the British Telecommunications Laboratories, Ipswich, U.K. as a Royal Research Fellow. His achievements to date include developing InP-based opto-electronic integrated circuits (OEICs), InP-based heterostructure field-effect transistors (HFETs) using E-beam lithography, and demonstrating the world’s first InP-based metamorphic heterojunction bipolar transistor (MHBT). A co-recipient of the 2007 Defence Technology Prize, Singapore for his outstanding contributions to the development of MMICs, Dr Wang was Session Chair in 2009 and Committee Member in 2010 of the IEEE International Electron Devices Meetings (IEDM), and Deputy General Chair of IEEE International Nanoelectronics Conference (INEC) in 2013. He has authored and co-authored over 260 technical papers, 2 book chapters and filed 2 patents. Dr Wang’s current research interests comprise III-V and Si Photonics, III-V devices and technology, micro- and nano-fabrication, RF Si MOS devices and technologies and RF MEMS.
