Beam steering through dynamic gain-loss modulation

In this work we have explored methods to improve gain in semiconductor nanostructures for designing active, PT-symmetric nanophotonic devices.

Optical Gain in Semiconductor Nanostructures

In this work, we have explored methods to improve gain in semiconductor nanostructures for designing active, PT-symmetric nanophotonic devices.

Spectral Singularities in PT-symmetric Metasurfaces

In this work, we have explored the novel concept of parity-time (PT) symmetry to realize a cavity that simultaneously acts as a gain media and provides high-Q for amplification at a sub-wavelength scale.
