Unidirectional BeamEmission fromConfocal Quasi- Stadium LaserDiodes

Unidirectional beamemission wasobtained fromstrained InGaAsP multiple-quantum- wellquasi-stadium laser diodes. Theunidirectional beamemission canbeexplained bythephase locking oftworesonator modeswithdifferent symmetry classes. ©2005 Optical Society ofAmerica OCIScodes: (140.3410) Laser resonators, (140.2020) Diode lasers
