Abstract: Provided is a semiconductor laser diode having a waveguide lens. The semiconductor laser diode includes at least one first waveguide having a narrow width, at least one second waveguide having a wide width wider, and at least one waveguide lens having an increasing width from the first waveguide toward the second waveguide and connecting the first waveguide to the second waveguide. Sidewalls of the waveguide lens connecting the first waveguide to the second waveguide may be curved. The second waveguide may be a waveguide providing an optical gain.
