I am Tushar Gaur, pursuing Ph.D. from Department of Elecrical Communication Engineering, Indian Institute of Science - Bangalore in the field of integrated optics. Currently I am working under the supervision of Prof. Talabattula Srinivas. I have major interest in curved guided structures like bent waveguide and ring resonator. Apart from that I am also working in the field of optial modulation and sensing. Before joining Ph.D. I have completed Mtech from Centre for Lasers and Photonics, Indian Institute of Technology- Kanpur. During my Mtech I was working in the field of optical trapping under the supervision of Prof. Debabrata Goswami, together we have discovered the effects of heating in optical trapping which has filled up a large gap between the experimental demonstration and theoritical simulations in the field of optical trapping. I have completed my Btech in Electrical and Communication Engineering from Rajasthan Technical University.
Outside research I am a traveller, finess enthusiast, swimmer and adventurer. I am also actively involved in biking and driving and keep on doing long rides and drives time to time, specially to scantuaries and reserved forest and wildlife areas.
With the increase in data rate and amount of information being exchanged faster and reconfigurable photonic circuits have become the need of the hour. Each circuit consists of a meshed connection of tunable basic units arranged a way that they can be reconfigured by the program for multiple applications simoultaneously.
Here are the highlights of some of the projects I am working on currently. Kindly click on the zooming in links to read more about them.
Multiple small rings can be arranged within a large ring for getting high FSR based modulation. Here we are talking about change of 0.5 nm in FSR for a change of 0.01 in coupling coefficient.

Bend waveguides have been interesting topic of research for many decades now. Recently we have simulated an on chip highly compact broad bandwidth easily fabricable mode converter whose conversion effeciency is very high in the telecom bandwith of 1500 nm to 1600 nm giving a conversion effeciency close to 99%.

Currently we are working on programmable photonic integrated circuits, which takes into account deep learning for training the circuit for performing multiple functions and also takes into account the routing algorithms to make a circuit reconfigurable according to need. This is a very nascent but rapidly emerging area and is going to be alternative to traditional FPGA circuits.
