  • Technique for a surface-emitting laser diode with a metal reflector
    Patent number: 6656756
    Abstract: The present invention is related to a method for fabricating a surface-emitting laser diode with a metal reflector. It is mainly the use of a combination of a metal reflector and wafer bonding technology to replace the traditional epiwafer process or high-temperature high-pressure wafer bonding technology in fabricating VCSEL Bragg Reflector. The metal reflector has high reflectance with its material selected to form ohmic contact with VCSEL material. Besides, the substrate for the metal reflector can be selected for cheap price and good heat dissipation. Further advantages include simple process, low production cost and good VCSEL characteristic etc.
