Abstract

We analyse the diffraction behaviour of a parity-time (PT) symmetric transmission grating. This kind of grating consists of a periodic structure with balanced real and imaginary parts of the refractive index. The bimodal interferometric operation (Mach-Zehnder like) is modified by the introduction of balanced gain and loss, leading to efficient switching around an exceptional point.
