Non-adiabatic Modal Dynamics around Exceptional Points in an All-Lossy Dual-Mode Optical Waveguide: Towards Chirality Driven Asymmetric Mode-Conversion
Arnab Laha, Abhijit Biswas, Somnath Ghosh
We report a 1D planar optical waveguide with transverse distribution of inhomogeneous loss profile, which exhibits an exceptional point (EP). The waveguide hosts two leaky resonant…
All-Lossy Quasi-Guided Dual-Mode Optical Waveguide Exhibiting Exceptional Singularities
Arnab Laha, Abhijit Biswas, Somnath Ghosh
We explore exceptional points (EP) in a dual-mode symmetric planar optical waveguide with transverse variation of inhomogeneous loss profile; where modal evolution alongside an EP…
Exceptional Points in an Specialty Microcavity: Interplay between State-Conversion and Cavity Control Parameters
Arnab Laha, Abhijit Biswas, Somnath Ghosh
Exploiting scattering-matrix in a gain-loss assisted optical-microcavity, interplay between asymmetric-state-conversion and cavity-control parameters around exceptional points is a…
