Enhanced light absorption in thin silicon photodetectors with photon-trapping structures

Photon-trapping micro- and nano-sized holes in silicon (Si) make normally incident light bend by almost 90°, making it propagate laterally along the plane and leading consequently to increased light absorption in the NIR band. Credit: Qarony, Mayet, et al., doi 10.1117/1.APN.2.5.056001. Photonic systems are quickly gaining traction in many emerging applications, including optical communications, lidar
