Blue vertical-cavity surface-emitting lasers (VCSELs) have experienced much progress recently. An electrically pumped ZnSe-based blue VCSEL with a SiO2/TiO2 dielectric multilayer mirror has been demonstrated. Electrically pumped lasing was achieved at 77K with a threshold current of 3mA. A low far-field radiation angle of 7°was observed above the threshold in a 10μm-diameter device, which indicates the spatial coherence expected for lasing.
