Abstract
Current confinement of ZnSe-based diode lasers on p-GaAs substrates has been achieved by ion bombardment. Nitrogen ions were used for the bombardment to produce a high-resistivity region in n-Zn(S)Se cladding layer. The threshold current was reduced by one-third with the introduction of this current-blocking region. The devices showed laser action up to 150 K under pulsed current injection.
