Types and Materials of Semiconductor Optical Modules
Abstract - Unlike other silicon based electronic devices, optoelectronic devices are primarily made from III-V semiconductor compounds such as GaAs, InP, GaN, GaP, GaSb, and their alloys since they are of direct band gap materials. Optoelectronics, a sub-discipline of photonics, involves the study and application of devices that emit, detect, or control light. Optical semiconductor devices are widely used, in fields ranging from optical fiber communication systems to consumer electronics, and have become indispensable devices in the equipment and systems making up the infrastructure of our society. An optical module usually consists of an optical transmitting device (TOSA, including a laser), an optical receiving device (ROSA, including a photodetector), functional circuits,main control circuit board (PCBA), housing and optical (electrical) interface and other components.
