LIGHT RECEIVING ELEMENT ARRAY, ONE-DIMENSIONAL LIGHT RECEIVING ELEMENT ARRAY, AND TWO-DIMENSIONAL LIGHT RECEIVING ELEMENT ARRAY

摘要

PROBLEM TO BE SOLVED: To provide a light receiving element array capable of discriminatingly receiving a plurality of wavelength ranges by a simple mechanism. SOLUTION: Disclosed is the light receiving element array on which light is made incident from an incident surface side and which detects it, the light receiving element array 10 including a light receiving layer of a compound semiconductor, a plurality of transmission films 7 disposed on the incident surface side of the light receiving layer and differing in transmission wavelength band, and a plurality of electrodes 12 individually capturing currents generated by a plurality of light receiving portions in the light receiving layer corresponding to the plurality of transmission films. The transmission films 7 are each composed of a single layer or a plurality of layers. COPYRIGHT: (C)2009,JPO&INPIT
