A surface emitting laser device is disclosed that is able to selectively
add a sufficiently large loss to a high order transverse mode so as to
efficiently suppress a high order transverse mode oscillation and to
oscillate at high output in a single fundamental transverse mode. The
surface emitting laser device includes a first resonance region that
includes an active layer and spacer layers, two distributed Bragg
reflectors that sandwich the resonance region, and a current confinement
structure that defines a current injection region for the active layer.
At least one of the distributed Bragg reflectors includes a second
resonance region arranged in the current injection region excluding a
predetermined region surrounding a center of the current injection
region.
