Photonic Integrated Circuit: Super Speed to Sensing

Dr. Shankar Kumar Selvaraja

Over the past decade, tremendous progress has been made in the area of the photonic integrated circuits (PIC). PIC is analogues to electronic IC, where properties of photons/light are manipulated to achieve desired optical process. Though the concept of manipulating light on a chip was conceived in the early eighties the year of revelation only happened at the turn of this century. Silicon-based photonic integrated circuit popularly known as Silicon photonics is a versatile platform for a wide range of applications. Backed by rich manufacturing infrastructure and process, it has become an industrial reality in a span of over a decade. In this talk, I would like to walk you through the developments that we have made in our research group in the area of high-speed optical interconnects, microwave photonics, and on-chip photonic sensor.

Dr. Shankar Kumar Selvaraja joined Centre for Nano Science and Engineering at IISc in 2014, as an Assistant Professor. His current area of research includes high-speed optical interconnect technology; integrated photonics, optical-PCB, Integrated photonic waveguides and device engineering, and device and material platform for on-chip photonic sensors. He obtained B.E. in Electronics and Communication Engineering from Bharathiar University, M.E. in Optical Communication from College of Engineering Guindy, Anna University, MSc. in Microelectronics and Microsystems from University of Twente, The Netherlands; and Ph.D. in Photonics Engineering from Ghent University, Belgium in 2011. His doctoral thesis was carried out at imec, Leuven, Belgium on wafer-scale fabrication technology for Silicon Photonic Integrated Circuits. Between 2011 and 2013, he worked as a post-doctoral researcher at imec and between 2013 and 2014, he worked at the same place as a silicon photonics-integration engineer. He has spent more than a decade in the area of Silicon and Integrated Photonics, developing state-of-the-art process, and device technology for CMOS compatible photonic circuits for high-speed optical interconnect and sensing applications. He has published over 150 research articles in international journals and conferences, and a total of 5 patents (US, EU and JP); 3 granted and 2 pending.
