Abstract: PROBLEM TO BE SOLVED: To conduct both current confinement and optical confinement in a vertical cavity surface-emitting laser and morover, to miniaturize the laser for array use, by a method wherein a high-refractive index mesa-shaped optical guide is formed in the laser. SOLUTION: A vertical cavity surface-emitting laser is provided with first and second multilayer mirrors 12 and 14 for forming an optical cavity resonator having the axis vertical to layers. An active region 16 and an optical guide 20 are installed on this resonator in the direction vertical to the axis. That is, the guide 20 is provided with a high-refractive index mesa, which is arranged across the axis of the resonator and is located in a cavity, and the multilayer dielectric (non-epitaxial) mirror 14 covering the mirror 12. For example, when pumping is properly conducted, radiation induced emission is generated in the region 16, this induced emission is propagated along the axis of the resonator and is outputted from the resonator as an output signal 40 through the mirror on one side of the mirrors. The guide 20, which has a comparatively high refractive index and is formed into the form of a mesa, does a working to form a lateral mode in a laser luminescence.
