    摘要: A vertical cavity surface emitting laser (VCSEL) having a first and a second mirror stack and an active region is formed utilizing epitaxial layer growth techniques. A lateral photodetector is integrally formed in the epitaxial growth layers, thereby providing for a VCSEL with laterally integrated photodetector. An isolation region is formed in the epitaxial growth layers between the VCSEL and the photodetector thereby isolating the VCSEL and the lateral photodetector. The integrated VCSEL and lateral photodetector capable of monitoring reflected laser emission, thus laser power output of the VCSEL and employing feedback to maintain a specific laser power output level, thereby capable of automatic power control (APC).

    摘要: A high efficiency vertical cavity surface emitting laser with first and second mirror stacks and an active area sandwiched therebetween. The second mirror stack is formed into a mesa with exposed end surface and outer sidewalls and a centrally located light emission region. A portion of the mesa adjacent the exposed outer sidewalls has a reduced electrical conductance so as to spread operating current from the outer sidewalls into the centrally located light emission region. The electrical conductance of the portion is reduced by oxidizing or etching the outer sidewalls.
