WebThis work reveals a class of non-Hermitian systems in which loss and gain are balanced robustly, thereby denoted as pseudo-Hermitian systems. 1 Introduction Conservation of energy is a fundamental concept that shapes our understanding of physical reality. WebOct 30, 2014 · In contrast to conventional ring cavity lasers with multiple competing modes, our parity-time microring laser exhibits intrinsic single-mode lasing regardless of the gain spectral bandwidth. Thresholdless parity-time symmetry breaking due to the rotationally symmetric structure leads to stable single-mode operation with the selective whispering ... WebApr 11, 2024 · 1 Introduction.
