Abstract :
This paper describes the characteristics of double-heterojunction GaAs/(AlGa)As laser diodes with the lowest room temperature threshold current density (475 A/cm2) yet reported and a very small temperature sensitivity. The CW output from such lasers is only halved between 22 and 80°C at constant current.
