VERTICAL CAVITY SURFACE EMITTING LASER HAVING INTENSITY |
摘要 |
A vertical cavity surface emitting laser having intensity control for maintaining a constant proportional output under varying conditions of the laser. A tilted window is situated over the laser output to reflect a portion of the light to a photo detector area. Signals representing light on the photo detector go to a feedback circuit which controls the power output of the laser. The tilted window has a metallic coating for partial reflection and for minimizing polarization effects on reflected and transmitted light. The photo detector has an anti-reflective coating for likewise minimizing polarization effects of the detected light. The VCSEL and photo detector are situated on the same substrate.
