Abstract

By mapping the scalar Helmholtz equation (SHE) to the Sch\"{r}odinger form we investigate the behaviour of PT\mathcal{PT} optical structure when the refractive index distribution nn admits variation in the longitudinal direction only. Interpreting the Sch\"{r}odinger equation in terms of a superpotential we determine the supersymmetric partners for nn. We also obtain new analytical solutions for the refractive index profiles and provide graphical illustrations for them.
