Paper Abstract
We present the design, technology and performances of a tunable Sb-based diode-pumped type-I quantum-well
vertical-external-cavity surface-emitting lasers emitting at 2.7μm. The half VCSEL structure was grown by MBE
with quantum-well growth temperature of 440 °C. The sample was thermally annealed to optimize the QW gain
design. We report on room-temperature continuous-wave laser with 0.17mW output power and low threshold
incident pump intensity of 0.7kW/cm2 while pumping at 830nm with a commercial diode laser. The external
cavity provides a circular TEM00 beam with a low divergence of 3.6°. The short mm-long optical cavity laser
exhibits tunable single frequency operation, with a side mode suppression ratio 23 dB, a linewidth 4GHz
and a linear light polarization. Thermal and optical properties are studied.
