Here we experimentally study PT-symmetric laser absorber in stripe waveguide. Using the concept of PT symmetry to exploit the light amplification and absorption, PT-symmetric laser absorbers have been successfully obtained. Different from the single-mode PT symmetric lasers, the PT-symmetric stripe ...

1D PT Symmetriclaser-absorber modesgainWe report the laser-absorber modes of a one-dimensional structure that constitutes layers of gain and loss. Transfer matrix method based simulations are employed to investigate the transmission characteristics of exact- parity-time (PT) and quasi-PT systems....
2D materialWe suggest graphene and a two-dimensional (2D) Weyl semimetal (WSM) as 2D materials for the realization of a broadband coherent perfect absorber (CPA) respecting overall PT-symmetry. We also demonstrate the conditions for mutually equal amplitudes and phases of the left and right ...
Alternatively, it is shown that coherent perfect absorber laser states are mediated by excitation of surface modes localised at all internal boundaries of the structure. The effects of the structure parameters and angle and direction of incidence on the resonant phenomena and spontaneous symmetry ...
CPA–laserAmong the interesting outcomes of the study of the physical applications of spectral singularities inPT-symmetric optical systems is the discovery of CPA–lasers. These are devices that act both as a threshold laser and a coherent perfect absorber (CPA) for the same values of their ...
