"A Single
Transvers-Mode Monolithically Integrated Long Vertical-Cavity
Surface-Emitting Laser," IEEE Photonics Technology Letters 17,
1366 – 1368 (2005)
We present a fully monolithic
long vertical-cavity surface-emitting laser operating in the fundamental
TEMoo transverse mode with output powers up to 7.8 mW. The lasing
wavelength is 980 nm and the threshold is 9.1 mA. Pump currents from
threshold to rollover produce an output beam with an M-2 < 1.08. The
laser consists of an InGaAs-GaAs-AlGaAs gain region/semiconductor mirror
bonded to a 0.5-mm-thick glass substrate with an integrated curved
mirror.
