LIGHT RECEIVING ELEMENT, LIGHT RECEIVING ELEMENT ARRAY, HYBRID DETECTOR, OPTICAL SENSOR DEVICE, AND METHOD FOR MANUFACTURING LIGHT RECEIVING ELEMENT ARRAY

摘要

PROBLEM TO BE SOLVED: To provide a light receiving element array having high light receiving sensitivity in a near-infrared region, a method for manufacturing the light receiving element array and the like.;SOLUTION: The light receiving element array includes: a light receiving layer 3 comprising a type II MQW; a cap layer 5; and a p-type region 6 reaching the light receiving layer from a surface of the cap layer. The type II MQW is (GaAsSb/InGaAs) or the like. The p-type region 6 comprises a high concentration region 6h and a sloped concentration region 6s. The high concentration region 6h is within the light receiving layer 3, and a pn junction 15 is formed within the light receiving layer.;COPYRIGHT: (C)2012,JPO&INPIT
