Heterostructure Injector Laser, Semiconductor Amplifying Element and a Semiconductor Optical Amplifier

摘要

heterostructure , the fiber-optic telecommunications and data communications systems, optical high-speed computing and switching systems , medical equipment, laser industrial equipment, injection is used in the laser frequency doubling of laser development , is used in the semiconductor amplifier , the manufacture of semiconductor injection emission source such as a semiconductor optical amplifier , and the pumping of fiber amplifiers and lasers in solid state . Heterostructure , the injection laser , the semiconductor amplifying device , and proposes a semiconductor optical amplifier , whose basic feature is in the modernization of the active region of the heterostructure and nuip area , and selecting a combination of location , compositions , refractive index and thickness of the heterostructure layers laser injection to the transient region can be formed can be controlled by the emission leak from the active layer , and to provide effective operation of the semiconductor amplifying element and semiconductor optical amplifier .
