Abstract

We propose the utilization of a ZnCdSSe quaternary alloy system as a material for a laser diode (LD) operating in the blue-green to ultraviolet spectral region. High quality cubic-structured ZnCdSSe quaternary alloys have been grown on a GaAs substrate by metalorganic molecular beam epitaxy (MOMBE). Optically pumped lasing action peaking at the vicinity of 465 nm at 70 K have been achieved by multilayered structures using ZnCdSSe alloys.
