๐ŸŽ™️Shaping Light, Shaping Futures: Innovation in Silicon Photonics | TSP | Guest - Prof. BIjoy Krishna Das




It’s not every day that you get to speak with the founder and chief investigator of a MEITY Centre of Excellence — on The Semiconductor Podcast, we had the rare privilege.
We were joined by Prof. Bijoy Krishna Das from IIT Madras๐Ÿ‡ฎ๐Ÿ‡ณ, a pioneer in Programmable Silicon Photonics — one of the most exciting frontiers in cutting-edge technology today. 
For the past 19 years, Prof. Das has been tirelessly working to establish a visionary “Product–Research–Development–Manufacturing” model in India. What makes his journey even more remarkable is his industry collaboration philosophy — working with mainstream players on an equal knowledge-sharing basis.
With a team of diligent researchers and an unwavering commitment, Prof. Das is well on his way to making CPPICS a global trendsetter.
As India dives deeper into the era of tech innovation, let’s take a moment to celebrate such contributions to the Make in India movement. ๐Ÿ‡ฎ๐Ÿ‡ณ
From his early journey in photonics to building one of India’s most advanced research hubs, Prof. Das shares how he's bringing to life a powerful “Product–Research–Development–Manufacturing” model ๐Ÿ’ก๐Ÿญ — right here in India.

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.
