Asymmetric Transmission in Photonic Structures with Phase-Change Components
arXiv:1806.07514 · doi:10.1103/PhysRevApplied.11.024046
Abstract
We consider the scattering problem for an asymmetric composite photonic structure with a component experiencing a thermally driven phase transition. Using a numerical example, we show that if the heating is caused by the incident light, the transmittance can become highly asymmetric within a broad range of light intensities. This effect can be utilized for directional light transmission, asymmetric optical limiting, or power switching.
