Abstract We report a self-induced spatially-coherent dot array consisting of fourteen units of vertical-cavity surface-emitting modes that exhibit spatially uniform spectra. A 47.5 µm total beam width and 0.5° narrow emission are achieved using an

This study obtained highly uniform and efficient GaN-based vertical-cavity surface-emitting lasers with curved mirrors from a single wafer. The average threshold current (I th) and the optical output power (P max) of 14 chips measured up to 7.0 mA we

A single cavity filtering mirror with a highly varying reflectivity spectrum was used to demonstrate a single longitudinal mode operation for a VCSEL with a ∼25 μm cavity length. The 443.5 nm lasing peak had an SMSR of 42 dB at 9 mA, 70 kA cm−2.

We demonstrate a room-temperature continuous-wave operation of green vertical-cavity surface-emitting laser (VCSEL) with a 20 μm long cavity possessing a dielectric curved mirror formed over a {20−21} semi-polar gallium nitride substrate. The emis

The continuous wave operation of a gallium-nitride-based vertical-cavity surface-emitting laser (GaN-based VCSEL) that uses boron ion implantation for lateral current confinement and a curved mirror for lateral optical confinement was investigated. T
