Blue laser diode (LD) structures with GaN waveguide layers and with In 0.03Ga0.97N waveguide layers were grown. A comparison study showed In0.03Ga0.97N waveguide layers significantly enhance the LD performance. The mechanism behind this was investigated using reciprocal space mapping of X-ray diffraction and time-resolved cathodoluminescence measurements. Room-temperature lasing of laser diodes at 454.6 nm was realized for LD structure with In0.03Ga0.97N waveguide layers.
