Room temperature photo-pumped lasing action of ZnCdSe/ZnSe/ZnMgSSe double heterostructure grown by metal-organic chemical vapor deposition

An internal loss of 4.6 cm -1 is estimated from the cavity length dependence of photo-pumped blue-lasing at room temperature (RT) with ZnSe/ZnMgSSe double- heterostructure (DH) grown by metal-organic chemical vapor deposition (MOCVD). Operation of the first blue-green laser diode grown by MOCVD has been demonstrated at 77 K under pulsed current injection. The laser consists of a ZnCdSe single quantum-well ZnSe optical guiding layers, and ZnMgSSe/ZnSSe dually-stacked cladding layers grown on a (100) n-GaAs substrate. 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/cm 2 ). The emission also shows a strong transverse electric polarization.
