Abstract
Remarkable reduction of the threshold current density is achieved in GaAs-GaAlAs distributed-feedback diode lasers by adopting a separate-confinement heterostructure. The diodes are lased successfully at temperatures up to 340°K under pulsed operation. The lowest threshold current density is 3 kA/cm2 at 300°K.
