Black silicon carbide ceramic based thermoelectric photodetector, optical power meter and optical energy meter

Abstract

A black silicon carbide ceramic based thermoelectric photodetector, and a thermoelectric optical power meter/thermoelectric optical energy meter using same. The black silicon carbide ceramic based thermoelectric photodetector comprises a thermal conduction plate (21) made of a black silicon carbide ceramic, wherein the surface of one side of the thermal conduction plate (21) is an optical absorption surface (211); and a thermopile (22) or a series connection conductive metal layer (302) is arranged on the surface of either side of the thermal conduction plate (21) to constitute the thermoelectric photodetector. In the thermoelectric photodetector, the black silicon carbide ceramic is used as both the thermal conduction plate (21) and a light absorber, and is directly combined with the thermopile (22) or the series connection conductive metal layer (302) to constitute the thermoelectric photodetector, thereby simplifying the structure of the thermoelectric photodetector.
