Photonic Jets for Strained-Layer Superlattice Infrared Photodetector Enhancement

Abstract

Photonic jets are light beams focused by dielectric microspheres down to subwavelength dimensions. In this workwe show that they can be used for enhancing performance of strained-layer superlattice (SLS) infrared (IR)photodiodes in the midwave-infrared spectral band (3-5 ?m). We optimized the design of these structures andexperimentally demonstrated the increased sensitivity compared to conventional photodetectors.
