Nowadays, many quantum-mechanical effects can be demonstrated with equivalent optical systems. As an example, a passive parity-time (PT) grating with separate modulation of the real and imaginary parts of the refractive index has been used to study the non-Hermitian parity-time symmetry. We construct such a passive PT grating in VirtualLab Fusion and analyze it with the Fourier modal method (FMM, also known as RCWA) to show its asymmetric diffraction property.

We construct a passive parity-time grating and analyze its diffraction properties with respect to selected grating parameters and the polarization of light.
