Abstract
A near-infrared vertical-cavity surface-emitting laser is provided, which utilizes a conventional distributed Bragg reflector and a complex Bragg reflector which consists of a dielectric Bragg reflector and a reflective metal layer to construct a cavity. With the disposition of a confining layer, the light emitted from an active layer is confined in the cavity to resonate so as to emit a laser light. The thickness of the complex Bragg reflector is much thinner than that of the conventional distributed Bragg reflector, thereby lowering the cost of manufacture. In addition, with the transfer method, the laser is transferred to the substrate with high thermal conductivity to increase the heat dissipation efficiency. Therefore, the present invention can maintain operation while emitting a high-power laser.
