Temperature Stability of InGaAlAs, InGaAsP, InGaAs and GaAs Quantum-wells for 852 nm Laser Diode
In order to enhance the temperature stability of 852 nm laser diode

InGaAs and GaAs quantum-wells were calculated by a comprehensive model theory
and the peak gain and wavelength versus operation temperature for the six different quantum-wells were compared and discussed. The results indicate that In

As single quantum-well 852 nm laser diode was grown by metal-organic chemical vapor deposition (MOCVD). The wavelength shift with temperature for 852 nm laser diode is 0.256 nm/K
the experimental results are in good agreement with theoretical calculation results.
