Integrated Optoelectronics Group  with Mr. Benjamin Lionel, Director of IRDE Deharadun (4th from right) - 10th October 2016

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).
