Abstract:
A vertical cavity surface emitting laser device includes a substrate, a first-type doped distributed Bragg reflector (DBR) disposed on the substrate, a first electrode disposed on the substrate, an active layer disposed on the first-type doped DBR, a second-type DBR disposed on the active layer, and a second electrode disposed on the second-type DBR. The second-type DBR defines a first doping concentration region, and a second doping concentration region disposed between the first doping concentration region and the active layer and that has a doping concentration less than that of the first doping concentration region. The second-type doped DBR has a confinement member formed in the first doping concentration region, and defining an aperture.
