Ultra-Thin Silicon Photonics Meta-Detector for Perfect 850-950 nm Band Tunable Absorption (JW1A.185)

Presenter: Roy Avrahamy, Ben-Gurion University of the Negev

We introduce a silicon photonics meta-detector for perfect 850-950nm band tunable absorption. Optimized <λ/4.5 thin designs of 10nm Si film wrapped by a laterally asymmetric dual SiO2-Air Si-SiO2 gratings cavity, fully absorbs light of >15µm penetration depth, in <25nm effectively thin Si absorber.
