BROADBAND UV-TO-SWIR PHOTODETECTORS, SENSORS AND SYSTEMS

摘要

Broadband photodetectors, detector arrays, sensors and systems, capable of detection and sensing ultraviolet (UV), visible (VIS) and shortwave infrared (SWIR) wavelengths of light, are disclosed. The devices may operate over a wavelength range between about 0.2 μm and 1.8 μm. In particular, the devices include a dilute nitride active layer with a bandgap within a range from 0.7 eV and 1 eV and a luminescent layer.
