PROBLEM TO BE SOLVED: To provide a vertical cavity surface emitting semiconductor laser and a surface emitting semiconductor laser array capable of controlling the polarization direction of laser beams. SOLUTION: In the surface emission semiconductor laser 100 in which a resonator 120 is formed on a semiconductor substrate 101 in the vertical direction and laser beams are projected in the vertical direction to the semiconductor substrate 101 from the resonator 120, the laser 100 contains a columnar section 110 as a part of the resonator 120 and an insulating layer 112 formed while being brought into contact with the external surface of the columnar section 110, and the insulating layer 112 has anisotropic stress resulting fro the plane shape of the insulating layer and controls the polarization direction of laser beams by the anisotropic stress.
