Provided are a multi-aperture optical detector that can address structural problems such as a complex signal wiring in array type optical detectors, and a need for a plurality of low noise amplifiers, signal to noise ratio detectors, etc., and an optical signal detecting circuit including the multi-aperture optical detector. The multi-aperture optical detector includes transmission lines having two output terminals; and a plurality of unit optical detectors which respectively have random polarities through the transmission lines and are connected in parallel, and optical signals from each of the unit optical detectors are added and output through the two output terminals. The multi-aperture optical detector has a high operation band width and can detect optical signals with a high sensitivity by connecting a plurality of unit optical detectors that respectively have a low optical detecting sensitivity and are physically compact and small. |
