Abstract
Greater than 150 degrees C CW lasing is achieved From an unbonded GaAs /AlGaAs VCSEL by employing high barrier confinement spacers and by blu e shifting the optical gain. This is done while maintaining a variatio n in threshold current of only +/-0.93mA over a range greater than 150 degrees C. These results are compared to a low barrier VCSEL of simil ar design.
