Abstract: A single wavelength semiconductor laser comprises a laser cavity portion and a mode selector portion. The laser cavity portion includes a waveguide and perturbation means for imparting a periodical perturbation to the waveguide. The laser cavity portion functions as a mode selecting reflective mirror for coupling two modes, which have different absolute values of propagation constants, to each other, accompanied with a mode conversion. The two coupled modes respectively travel forward and rearward along the waveguide to constitute two degenerate laser resonance modes. The mode selector portion selectively outputs a predetermined laser resonance mode out of the two degenerate laser resonance modes, and the mode selector portion is structured so that light returing to the semiconductor laser from outside can be coupled only to the other of the two degenerate laser resonance modes. Thus, a dynamic single wavelength semiconductor laser is obtained, which is insensitive to returning light, even without use of any isolator.
