Emission Characteristics of InGaN/GaN Vertical-Cavity Surface-Emitting Lasers

Lasing characteristics of optically pumped GaN-based vertical-cavity surface-emitting lasers were investigated. The laser emission showed single and multiple spots emission patterns with spectral and spatial variation under different pumping conditions.
