Silicon Photonics @ IIT Madras

Since its inception in January 2007, the Integrated Optoelectronics Group has been actively engaged in novel design, fabrication and characterizations of integrated silicon photonic devices and circuits for communications, high performance computations and sensing applications.

The group is now equipped with micro/nano fabrication facilities (Centre for NEMS and Nanophotonics) and device characterization facilities (Integrated Optoelectronics Lab).

We are looking for bright and motivated PhD candidates for pursuing research in following topics:

(1) Silicon Photonics Devices for Quantum Computation and Communications;

(2) Silicon Photonics Devices for RF Signal Processing;

(3) Silicon Photonics Lab-On-Chip for Bio-Sensing;

Interested candidates with M.Tech/MS Degree in ECE/EE/Applied Physics  backgrounds may directly contact Prof. Bijoy Krishna Das (E-Mail: bkdas@ee.iitm.ac.in)
