InGaN Quantum-Well Laser Diode Achieves CW Operation
Researchers from Xerox's Palo Alto Research Center in California have demonstrated continuous-wave (CW) operation of InGaN quantum-well laser diodes at room temperature.
The quantum wells were grown on sapphire substrates using organic chemical vapor deposition.
To achieve CW lasing, the group used a series of conventional ridge waveguide devices with etched mirrors and highly reflective coatings.
