Abstract
All molecular beam epitaxy grown planar top emitting AlGaAs/GaAs multi-quantum well lasers were fabricated and characterized. The vertical cavity surface emitting laser (VCSEL) consists of GaAs/Al0.2Ga0.8As (100/80 A) quantum wells sandwiched between two two-step doped distributed Bragg reflector. Gain-guided VCSELs operate continuous wave up to 90°C with a characteristics temperature of 210°K and can be modulated at frequency above 5 GHz. Thresholds as low as 2 mA and CW powers more than 2 mW were obtained at room temperature. Monolithic integration of a PIN photodetector on top of the VCSEL is also demonstrated and discussed. The integrated photodetector shows a linear response to the laser emission with an effective responsitivity of 0.25 A/W.
