Machine prediction of topological transitions in photonic crystals
Bei Wu, Kun Ding, C. T. Chan +1
We train artificial neural networks to distinguish the geometric phases of a set of bands in 1D photonic crystals. We find that the trained network yields remarkably accurate predi…

General coupled mode theory in non-Hermitian waveguides
Jing Xu, Yuntian Chen
In the presence of loss and gain, the coupled mode equation on describing the mode hybridization of various waveguides or cavities, or cavities coupled to waveguides becomes intrin…
