Hosting Second Order Exceptional Point in an All-lossy Dual-Core Photonic Crystal Fiber
Shamba Ghosh, Arpan Roy, Bishnu P. Pal +1
We report an all-lossy index-guided dual-core photonic crystal fiber (PCF) that hosts a second-order exceptional point (EP) in the systems parameter space. By appropriately selecti…

Dynamically Encircled Higher-order Exceptional Points in an Optical Fiber
Arpan Roy, Arnab Laha, Abhijit Biswas +3
The unique properties of exceptional point (EP) singularities, arising from non-Hermitian physics, have unlocked new possibilities for manipulating light-matter interactions. A tai…
