Ultra-thin Silicon Photonics Meta-detector for Perfect 850-950 nm Band Tunable Absorption
2021 CONFERENCE ON LASERS AND ELECTRO-OPTICS (CLEO)（2021）
Abstract
We introduce a silicon photonics meta-detector for perfect 850-950 nm band tunable absorption. Optimized < lambda =4.5 thin designs of 10 nm Si film wrapped by a laterally asymmetric dual SiO2-Air Si-SiO2 gratings cavity, fully absorbs light of > 15m m penetration depth, in < 25 nm effectively thin Si absorber.
