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…
