The Study on the Lasing Modes Modulated by the Dislocation Distribution in the GaN-Based Microrod Cavities
Low-threshold lasing under pulsed optical pumping is demonstrated in GaN-based microrod cavities at room temperature, which are fabricated on the patterned sapphire substrates (PSS). Because the distribution of threading dislocations (TDs) is different at different locations, a confocal micro-photol...
