Abstract

Operation of the first blue-green laser diode grown by metal organic chemical vapour deposition (MOCVD) has been demonstrated at 77 K under pulsed current injection. The observed stimulated emission is at a wavelength of 473 nm. With threshold current ranging from 90 to 180 mA (0.9-1.8 kA/cm²), and threshold voltage of ~13.0 V. The emission also shows a strong transverse electric polarisation. The laser consists of a ZnCdSe single quantum-well, ZnSe optical guiding layers, and ZnMgSSe-ZnSSe dual-stacked cladding layers grown on a (100) n-GaAs substrate
