CMOS‐Compatible Short‐Wave Infrared Linear Arrays of Ge‐on‐Si Avalanche Photodiodes

Advanced Photonics Research, EarlyView.
The fabrication and characterization of a new type of surface‐illuminated Si‐based avalanche photodiode array operating in the short‐wave infrared region using germanium as the absorber and silicon as the multiplier is reported. The demonstration of an avalanche gain of 24 at a temperature of 378 K allows the devices to operate in outdoor environments.

State‐of‐the‐Art Solar Blind and X‐Ray Photodetectors Based on Gallium Oxide

Advanced Photonics Research, EarlyView.
State‐of‐the‐art Ga2O3‐based solar‐blind UV and X‐ray photodetectors (PDs) are reviewed. Benchmark plots compare responsivity versus specific detectivity for UV PDs (photoconductors, photovoltaic, Schottky, heterojunction, avalanche, and phototransistor types) and sensitivity versus response time for X‐ray detectors based on Ga2O3 bulk crystals, thin ...

High‐Resolution On‐Chip Digitally Tunable Spectrometer Based on Double‐Cascaded Ring Resonators

Advanced Photonics Research, EarlyView.
An integrated spectrometer is here presented, based on two cascaded ring resonators covered with a phase change material. The Vernier architecture is implemented allowing for a digital scan of wavelengths. Resolution smaller than 0.1 nm can be achieved, together with a footprint ≈0.03 mm2 and a bandwidth of the order of tens of nanometers.
