Guest : Professor Bijoy Krishna Das

Prof. Dr. Bijoy Krishna Das joined the Department of Electrical Engineering at IIT Madras as an Assistant Professor in 2006 and has since pioneered the development of silicon photonics research in India. At a time when IMEC Belgium had just initiated Silicon Photonics MPW runs with limited PDK offerings, he laid the groundwork for indigenous technology development, establishing in-house capabilities in silicon photonics design, fabrication, and characterization. His vision was to expose Indian students and researchers to CMOS-compatible silicon photonics, enabling them to make impactful contributions at a time when core engineering opportunities were scarce. Over the years, he has mentored seven Ph.D. scholars, fifteen MS (by research) students, and guided over 25 BTech/MTech projects, many of whom are now contributing to advanced semiconductor R&D globally. His leadership led to the establishment of India’s first Silicon Photonics Centre of Excellence—CPPICS—at IIT Madras, supported by MeitY, and he is also a founding member of the Centre for NEMS and Nanophotonics (CNNP). Currently, he leads a vibrant research group under the mission "Silicon Photonics Enabled Quantum Photonic Integrated Circuits and Systems (SPEQCS)," mentoring a team of postdoctoral researchers and scholars dedicated to advancing quantum photonic technologies.
