Abstract
We report on the first room temperature continuous wave operation of t he double heterostructure optoelectronic switching laser implemented a s a vertical-cavity laser. A deposited dielectric top reflector of SiO 2/TiO2 allowed the use of a cavity etch back technique after the sampl e was grown to position the cavity mode at the desired wavelength. Roo m temperature CW threshold currents as low as 4.8 mA for a 14 mum diam eter device was obtained with slope efficiencies of 0.45 mW/mA. The ma ximum CW output power was 2.5 mW and the resistivity was 4 x 10(-4) OM EGAcm2.
