Retroreflection Using Bloch Surface Wave Resonance for External Laser Mirror
2023 IEEE CPMT Symposium Japan (ICSJ)(2023)
Abstract
A narrowband retroreflector consisting of a dielectric multilayer is designed for both retroreflecting a diverging incident wave from a semiconductor optical amplifier and supporting a Bloch surface wave. The retroreflectance is predicted to be 56%.
