Research Overview
At Phononlab, we explore light-matter interactions through the lens of nonlinear optics. We study the effect of nonlinear optical phenomena in microresonators, nanowires, and waveguides compatible with standard fiber optics platforms. We also study the interaction of light and radio or microwaves and explore their physics to contribute to the field of communications.

Latest News & Events
1 JRF, 1 full-time PhD, and 1 Research Associate position will soon be available for developing a Photonics Quantum Processor
under the National Quantum Mission.
Interested candidates can email me at rpant@iisertvm.ac.in​
​
For Postdoctoral positions, experimental experience with microresonators, nonlinear optical phenomena e.g. four-wave mixing, parametric down- and up-conversion, quantum entanglement measurement techniques, single-photon detection is required along with experience in using COMSOL for optical modes and dispersion calculation.

Microresonator Brillouin laser and multi-Stokes generation at 2 µ m
A low threshold, tunable, stable narrow-linewidth 2 um Brillouin laser and cascaded higher-order Stokes lasers were demonstrated in a silica microsphere platform. This work may find applications in optical communications, soliton combs, and atmospheric sensing in the 2-um wavelength region.
