Abstract :
Whispering gallery mode operation has been observed from a broad-area oxide-confined tunable vertical cavity laser structure which uses an airgap between the top mirror and the semiconductor active layer. Strong index guiding from both the air gap and the AlAs native oxide supports this mode of operation over a wide range of injection currents
