Patent ID: 7620089

Claim:
A surface emitting type semiconductor laser, comprising: a lower mirror; an active layer formed on the lower mirror; and an upper mirror having a plurality of pairs of conductive layers formed above the active layer, the upper mirror including a first region, a second region formed inside the first region, and a current aperture, the first region having a first hole portion and a first non-hole portion, the first hole portion having a plurality of holes, the first non-hole portion formed between the first hole portion and the active layer, and having 13 to 18 pairs of the conductive layers, the second region being in a circular shape as viewed in a plan view, the circular shape being formed with a radius where an energy increasing rate in the active layer is positive with respect to a zeroth-order mode and is negative with respect to a first-order mode, the radius of the circular shape being less than 62% of a radius of an opening section of the current aperture.
