Abstract:
Provided are: an optical waveguide that relatively easily expands a spot size and that can suppress an increase in optical coupling loss with another optical waveguide element; and an optical component and variable-wavelength laser that use the optical waveguide. The optical waveguide is provided with: a cladding member; and a core layer that is disposed within the cladding member and that is formed as an elongated body having a rectangular cross-sectional shape from a material having a higher refractive index than the material configuring the cladding member. Here, the cross-sectional shape of the core layer is characterized in having a rectangular shape in which the length in the lateral direction is at least 10 times the length in the vertical direction.

Claim (Index 11):
An optical waveguide including a cladding member; and a core which is disposed in the cladding member and is formed into an elongated body having a rectangular cross-sectional shape from a material having a refractive index higher than that of a material constituting the cladding member, wherein the cross-sectional shape of the core is a flattened rectangle having a length in a width direction 10 times or more as a length in a thickness direction, wherein\n the core is forming into tapered shape varying in width along an elongation direction and in such a way that the cross-sectional shape of the core is narrowed in a width direction toward an end region of the core, the end region of the core being coupled to a compound semiconductor amplifier, and wherein the core has a constant thickness.
