TL;DR: In this paper, surface microstructuring using laser-chemical etching was used to increase the absorptance of light by silicon to approximately 90% from the near ultraviolet (0.25 μm) to the near infrared (2.5 μm).
Journal ArticleDOI
Enhancing near-infrared avalanche photodiode performance by femtosecond laser microstructuring
TL;DR: Experimental results provided evidence to suggest that the improvement in charge collection is a result of increased absorption in the near-IR.
Proceedings ArticleDOI
Near Infrared Receiver for Advanced Ophthalmology
TL;DR: Research is presented on the development of an optical receiver module with a wide frequency bandwidth and excellent response to near-infrared radiation, being produced to promote new imaging modalities, allowing retinal specialist to utilize established diagnostic instruments in a unique or more effective manner.
