Refractive index profiles for a $\mathcal{P}\mathcal{T}$-symmetric optical structure

Bijan Bagchi, Rahul Ghosh, Sauvik Sen

By mapping the scalar Helmholtz equation (SHE) to the Schrodinger form we investigate the behaviour of $\mathcal{P}\mathcal{T}$ optical structure when the refractive index distribution $n$ a…
