Abstract
A semiconductor laser device comprising: a ring-shaped resonator constituted by a square-shaped optical waveguide composed of four straight optical waveguide sides in which facing sides are positioned in a parallel manner and a reflecting mirror is formed at each of the four corners of said square-shaped optical waveguide in a manner to divide the intersection angle of two each of said four sides at each of said four corners into two equal parts, and a means, for releasing laser light from said ring-shaped resonator, which is disposed on or near a part or the whole area of at least one of said four sides of said square-shaped optical waveguide.
Claims6
In a semiconductor laser device comprising a ring-shaped resonator,
- said ring-shaped resonator is constituted by a square-shaped optical waveguide composed of four straight optical waveguide sides in which facing sides are positioned in a parallel manner and a reflecting mirror is formed at each of the four corners of said square-shaped optical waveguide in a manner to divide the intersection angle of two each of said four sides at each of said four corners into two equal parts, and
- a means for releasing laser light from said ring-shaped resonator is disposed near a part of at least one of said four sides of said square-shaped optical waveguides, at least one portion of said means being optically coupled with at least one of said four sides of said square-shaped optical waveguides.
