PT-symmetric laser absorber In a recent work, Y. D. Chong et al. Phys. Rev. Lett. 105 053901 (2010) proposed the idea of a coherent perfect absorber (CPA) as the time-reversed counter... Stefano,Longhi - 《Physical Review A》 被引量: 179发表: 2010年 PT-symmetric laser absorber In...
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 ...

Non-Hermitian parity-time (\({{{\mathcal{P}}}{{{\mathcal{T}}}\)) and anti-parity-time (\({{{\mathcal{APT}}}\))-symmetric systems exhibit novel quantum properties and have attracted increasing interest. Although many counterintuitive phenomena in \({{{\mathcal{P}}}{{{\mathcal{T...
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 ...

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 ...
