Surface waves at the interface with an antisymmetric gain/loss profile
Original language description
We studied properties of strongly guiding two-mode waveguides with antisymmetric gain/loss profile which constitute photonic analogues of quantum mechanical structures with parity-time symmetry breaking. For both TE and TM polarizations, the dependencesof effective indices of the guided modes vs. gain/loss coefficient exhibit a degenerate critical point that defines two regimes with profoundly different behavior. In addition, we have shown that the interface between the two media supports propagation of a strongly confined non-attenuated TM polarized surface wave. We examined the properties of the surface wave obtained by both the modal and FDTD method and discuss the differences between the results obtained by both techniques as both the material andgeometrical parameters are varied.
