Dr. Srikanth Sugavanam

Scientist, Photonics and Applications


My name is Srikanth, and I am an Assistant Professor with the School of Computer and Electrical Engineering at IIT Mandi, India.

I work in the area of fibre lasers, specializing in real-time laser characterization techniques. I am keenly interested in applying such techniques in real-world applications, where multi-gigahertz bandwidth, megahertz-rate acquisition diagnostics can lead to interesting insights.

Analysis of Laser Radiation using the Nonlinear Fourier Transform

We demonstrate how the Nonlinear Fourier transform (NFT) based on the Zakharov-Shabat spectral problem can be applied as a signal processing tool for representation and analysis of coherent structures embedded into dispersive radiation in lasers.
