Ultra-Thin Tunable Absorbers Based on Lossy Phase-Change Materials

Optica Advanced Photonics Congress, pp. NoW4C.2

Abstract

We demonstrate ultra-thin, switchable infrared absorbers based on thin layers of PCMs with high optical contrast between a lossless amorphous and an exceptionally lossy crystalline phase on top of polar substrates.
