Light-induced optical switching in an asymmetric metal-dielectric microcavity with phase-change material
R. Thomas, A. A. Chabanov, I. Vitebskiy +1
We propose an infrared power switch based on an asymmetric high-Q microcavity incorporating a metallic nanolayer in close proximity to a layer made of a phase-change material (PCM)…
Unidirectional Photonic Circuit with Phase-Change Fano Resonator
Roney Thomas, Eleana Makri, Tsampikos Kottos +2
We demonstrate that the integration of a phase-change material (PCM) in one of the two microresonators of a photonic metamolecule, coupled to a bus waveguide, can lead to unidirect…
Self-Regulated Transport in Photonic Crystals with Phase-Changing Defects
Roney Thomas, Fred M. Ellis, Ilya Vitebsky +1
Phase changing materials (PCM) are widely used for optical data recording, sensing, all-optical switching, and optical limiting. Our focus here is on the case when the change in th…
Giant Non-reciprocity Near Exceptional Point Degeneracies
Roney Thomas, Huanan Li, F. M. Ellis +1
We show that gyrotropic structures with balanced gain and loss that respect anti-linear symmetries exhibit a giant non-reciprocity at the so-called exact phase where the eigenfrequ…
