Abstract
A method of manufacturing a polarization switching surface-emitting laser in which a laser resonance wavelength depends on changing the polarization of the laser, by changing the refractivity of a compound semiconductor mirror layer of the laser depending on polarizations using an electro-optic effect of compound semiconductor materials such as GsAs and applying an electric field thereto.
