Recovering parity-time symmetry in highly dispersive coupled optical waveguides
Coupled photonic systems satisfying parity-time symmetry (PTS) provide flexibility to engineer the flow of light including non-reciprocal propagation, perfect laser-absorbers, and ultra-fast switching. Achieving the required index profile for an optical system with ideal PTS, i.e. $n(x)=n{(-x)}^{* }...
