Compound-Source Molecular Beam Epitaxy for ZnCdSe/ZnSSe/ZnMgSSe Laser Structure

Abstract
We have developed compound-source molecular beam epitaxy (CSMBE) for ZnSe-based laser diodes. The CSMBE technique employs compound sources instead of elemental sources, and can reduces the number of growth parameters. Continuous-wave operation at room temperature of ZnCdSe/ZnSSe/ZnMgSSe laser diodes grown by CSMBE has been demonstrated. The threshold current was 68 mA for a gain-guided device 5 µm wide and 750 µm long.
