Surface emitting laser and ranging device

Abstract

Provided is a surface emitting laser capable of obtaining desired characteristics while suppressing occurrence of structural defects. A surface emitting laser according to the present technology includes a resonator including: a first structure including a substrate and a first reflector stacked on each other; a second structure that includes a second reflector and is disposed on a side of the first structure corresponding to the first reflector; and an intermediate structure that includes an active layer and is disposed between the first and second structures, in which the substrate includes a material having a lattice constant that is greater than a lattice constant of GaAs and less than a lattice constant of AlAs, and the first reflector and the intermediate structure include different material systems. According to the present technology, it is possible to provide a surface emitting laser capable of obtaining desired characteristics while suppressing occurrence of structural defects.
