Unidirectional transmission in 1D nonlinear photonic crystal based on topological phase reversal by optical nonlinearity

AIP Advances, 2017
We propose a scheme of unidirectional transmission in a 1D nonlinear topological photonic crystal based on the topological edge state and three order optical nonlinearity.

Spatiotemporal Photonic Crystals

Conference on Lasers and Electro-Optics, 2020
We study photonic systems periodic in both time and space - spatiotemporal photonic crystals, and find that their bandstructure contains both frequency and momentum bandgaps. When the two types of bandgaps coincide, anomalous bandstructure is observed.
