Defect in Photonic Time Crystals
Snehashis Sadhukhan, Somnath Ghosh
Photonic Time Crystals (PTCs) provide a completely new platform exhibiting light wave amplification owing to periodically varying electromagnetic properties. The need to control th…

Momentum controlled optical pulse amplification in photonic time crystals
Snehashis Sadhukhan, Somnath Ghosh
We show that by manipulating the momentum (k) of a propagating optical pulse, the intensity can be controlled and highly enhanced in a linear binary photonic time crystal (PTC) sys…

Photonic Crystal Based Ultra-Sensitive Interferometric Sensor with Spatial Resolution up to 1 nm
Snehashis Sadhukhan, Arnab Laha, Abhijit Biswas +1
We report a very high precision interferometric sensor with resolution up to ~λ/1024, exploiting hollow photonic bandgap waveguide-based geometry for the first time. Here sensing h…
