Contrasting Spectral Signatures and Sensitivities of CPA-Lasing in a $P T$ -Symmetric Periodic Structure

Li Ge, Liang Feng

The CPA-laser is a coexisting state of coherent perfect absorption and lasing that was proposed in parity-time ( $P T$ ) symmetric photonic systems. In this work we show that the…

Optical Reciprocity Induced Symmetry of the Scattering Eigenstates in Non- $P T$ -Symmetric Heterostructures

Li Ge, Liang Feng

The scattering matrix $S$ obeys the unitary relation $S^{†} S = 1$ in a Hermitian system and the symmetry property $P T S P T = S^{- 1}$ in a Parity-Time ( $P T$ ) sym…
