Abstract :
Photonic jets are light beams focused by dielectric microspheres down to subwavelength dimensions. In this work we 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 μm). We optimized the design of these structures and experimentally demonstrated the increased sensitivity compared to conventional photodetectors.
