TUNNEL JUNCTION PHOTONIC CRYSTAL LASER WITH NARROW VERTICAL FAR-FIELD DIVERGENCE ANGLE

摘要

Provided is a tunnel junction photonic crystal laser, comprising: a substrate; and a plurality of laminated structures successively formed on the substrate, wherein each of the laminated structures comprises an active layer and a photonic crystal layer, and a tunnel junction is formed between adjacent laminated structures. According to the tunnel junction photonic crystal laser of the present disclosure, the peak power is improved, the detection range of the laser is increased, the laser output with a narrow vertical far-field divergence angle at the peak power is realized, and the tunnel junction photonic crystal laser has broad application prospects in the fields of laser ranging, laser imaging, laser radar, etc.
