Abstract
A horizontal cavity surface emitting laser device includes an active layer configured to generate light to be emitted in one direction along the one surface of a semiconductor substrate and in another direction opposite to the one direction. The device also includes a rear distributed Bragg reflector unit configured to reflect the light. The rear distributed Bragg reflector unit includes a waveguide layer configured to guide light and a distributed Bragg reflector configured to reflect the light in the waveguide layer. The device further includes an optical component configured to guide, in a direction different from the one direction and the other direction, the light emitted from an end of the rear distributed Bragg reflector unit in the one direction. The device further includes a front reflecting mirror configured to reflect the light emitted from the active layer in the other direction toward another surface side of the semiconductor substrate.
