Characteristics of native-oxide-confined InGaP-(Al/sub x/Ga/sub 1-x/)/sub 0.5/In/sub 0.5/P quantum-well ridge waveguide lasers We report 670-nm native-oxide confined GaInP-(Al/sub x/Ga/sub 1-x/)/sub 0.5/In/sub 0.5/P quantum-well ridge waveguide laser diodes. The devices are ...
Results achieved on the operation of short-wavelength InGaAlP visible-light laser diodes are described. It is found that there is a strong correlation between operation temperature and oscillation wavelength. The deterioration of favorable temperature characteristics in the short-wavelength region is attribu...
