DOI: 10.1063/5.0276520

Abstract: We investigate the microdynamics of MXene (Ti3C2Tx) flakes under the influence of two opposing effects: light-induced alignment and Brownian motion. The interplay between these effects gives rise to spatial self-phase modulation patterns. Light-induced alignment initiates… read more here.

DOI: 10.1364/oe.532547

Abstract: Exceptional points (EPs) display peculiar degeneracies, where complex eigenvalues and associated eigenvectors coalesce simultaneously, resulting in a defective Hamiltonian. Meanwhile, the negative imaginary part of the energy eigenvalues related to a finite spectral linewidth at… read more here.

DOI: 10.1364/ol.482635

Abstract: Optical isolators are an essential component of photonic systems. Current integrated optical isolators have limited bandwidths due to stringent phase-matching conditions, resonant structures, or material absorption. Here, we demonstrate a wideband integrated optical isolator in… read more here.
