Dual-state control of lasing and absorption via conjugate exceptional points
Arnab Laha, Somnath Ghosh, Adam Miranowicz +1
Lasing and coherent perfect absorption (CPA) are time-reversed manifestations of non-Hermitian light-matter interactions. While exceptional points (EPs) have been extensively explo…
Higher order Conjugate Exceptional Points in an 1D Photonic Bandgap Waveguide
Sibnath Dey, Harish N S Krishnamoorthy, Somnath Ghosh
We demonstrate third-order conjugate exceptional points (EPs) in a gain-loss assisted multi-mode 1D complementary photonic bandgap waveguide. Our study reveals the higher-order mod…
Parametrically encircled higher-order exceptional points in anti-parity-time symmetric optical microcavities
Dinesh Beniwal, Arnab Laha, Adam Miranowicz +1
The fascinating realm of non-Hermitian physics with the interplay of parity (P) and time-reversal (T) symmetry has been witnessing immense attention in exploring unconventional phy…
Correlated Nonreciprocity around Conjugate Exceptional Points
Arnab Laha, Adam Miranowicz, R. K. Varshney +1
The occurrence of exceptional points (EPs) is a fascinating non-Hermitian feature of open systems. A level-repulsion phenomenon between two complex states of an open system can be…
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…
