Incoherent broadband mid-infrared detection
WebJun 11, 2024 · Optical phased arrays (OPAs) are essential optical elements in applications that require the ability to manipulate the light-wavefront, such as beam focusing and light steering. To miniaturize the optical components, active metasurfaces, especially graphene metasurfaces, are used as competent alternatives. However, the metasurface cannot … WebNov 16, 2024 · Traditional detection approaches are based on the linear absorption of MIR light by small-bandgap semiconductors, such as mercury cadmium telluride (MCT) or indium antimonide (InSb). Such single element or matrix arrays are susceptible to thermal noise and thus require active cooling, often down to cryogenic temperatures.
