同年,Stefano Longhi提出了将CPA和激光结合起来的方案,这类器件可同时实现相干完美吸收和相干波的出射,即PT对称激光吸收体(PT-symmetric laser absorber)。鉴于完美吸收这种突破性的特性,这两种方案为之后的广泛应用奠定了基础。 (CPA也是更早一些的啁啾放大技术的缩写) 参考:Phys. Rev. Lett. 105, 053901 (2010) ...

Experimental realization of PT-symmetric optical systems [2] has prompted several proposals [3], one of which is the proposed Coherent Perfect Absorber (CPA), with only time reversal (T) symmetry. It shows perfect absorption of two laser beams, incident from two opposite directions, with ...
45Altmetric Metrics Abstract In recent years, notions drawn from non-Hermitian physics and parity–time (PT) symmetry have attracted considerable attention. In particular, the realization that the interplay between gain and loss can lead to entirely new and unexpected features has initiated an intense...

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...
Symmetric and linear IDS − VDS curves, as seen in the insets in the main figures, suggest a better quality of FET devices with an ohmic nature of the contacts. The current on/off ratio estimated from transfer curves (IDS vs. Vg) is found to be ~105 at VDS = 1 V ...
