Exceptional points and asymmetric mode conversion in quasi-guided dual-mode optical waveguides
Non-Hermitian systems host unconventional physical effects that be used to design new optical devices. We study a non-Hermitian system consisting of 1D planar optical waveguides with suitable amount of simultaneous gain and loss. The parameter space contains an exceptional point, which can be access...
