Abstract

PURPOSE:To easily constitute an optical system for a photodetector with small photodetection area by providing a tapered optical waveguide between the image plane of reception optical system and the photodetection surface of the photodetector. CONSTITUTION:The tapered optical waveguide 14 is provided between the image plane of the reception optical system 5 and the photodetection surface of the photodetector 6. Luminous flux converged on the image plane of the reception optical system 5 is further converted small on the photodetection surface of the photodetector 6 by the optical waveguide 14.
