5-1. Types of Optical Semiconductors

The types of optical semiconductors are as follows :
(1)Light-emitting device ・・・visible-light LED, infrared LED, ultraviolet LED, laser diode
(2)Light-receiving device・・・photosensor, solar cell, CMOS sensor
(3)Composite device(combination of light-emitting element and light-receiving element alignment)・・・photocoupler, fiber coupler
