Integrated Photonics Devices and Circuits

By Prof. Bijoy Krishna Das   |   IIT Madras
Learners enrolled: 172
Lightwave technology and photonics played an important role in the progress of long-haul fiber optic communication systems. Recent advances in CMOS compatible silicon photonics technology has made it feasible for on-chip high-speed optical interconnects, biomedical lab-on-chip sensors, microwave photonics system-on-chip, linear optical quantum computing (LOQC) and highest degree of secured quantum key distribution (QKD) photonics chips with large-scale integrated components. In this course, students will learn theory of integrated optical waveguides and working principles of various integrated photonics devices (passive and active). The design rules and technology for large-scale photonic integrated circuits will be also addressed in this course.

Instructor bio

Prof. Bijoy Krishna Das

IIT Madras
Bijoy Krishna Das received his Master Degree in Solid State Physics from Vidyasagar University, West Bengal, India, in 1996, and Ph.D. Degree (Dr.rer.nat) in Applied Physics from the University of Paderborn, Germany in April 2003. From 1996 to 2006, he was working in the area of LiNbO3 based integrated optics, which includes three years of pre-doctoral research at Microelectronics Center, IIT Kharagpur, India; four years of doctoral research with the Department of Applied Physics, University of Paderborn, Germany; and three years of postdoctoral research in three different countries (Japan, USA and Germany). His first postdoctoral assignment was offered as an FRC Fellow with the Graduate School of Engineering, Osaka University, Osaka, Japan, from 2004 to 2005. He later moved for his second postdoctoral research at the Center for Optical Technologies, Lehigh University, Bethlehem, PA, USA. In April 2005, he returned back to the University of Paderborn, where he joined as a Wissenschaftlicher Mitarbeiter and continued his postdoctoral research on integrated nonlinear photonic devices. He also worked for a while with the Laboratoire Aime Cotton, CNRS, Orsay, France. Since August 2006, he has been with the Department of Electrical Engineering, IIT Madras, Chennai, India, where he is currently a full Professor. His current research interest is in the area of CMOS compatible silicon photonics integrated circuit design, fabrication and testing. He has published more than one hundred research articles in various International Journals and Proceedings of International Conferences.
