For the first time, 860 nm gain-guided top surface emitting lasers (SEL) that operate continuous wave up to 90 degrees C and can be amplitude modulated at frequencies beyond 5 GHz are demonstrated. Laser thresholds as low as 2 mA and output powers more than 1 mW were obtained at room temperature. Singlemode emission with sidemode suppression greater than 50 dB was also observed. The higher operating...
