摘要	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.
其他摘要	本发明提供一种光波导，其相对容易地扩大光点尺寸，并且能够抑制与另一光波导元件的光耦合损耗的增加。以及使用光波导的光学元件和可变波长激光器。光波导设有：包层构件;芯层设置在包层构件内，并且由折射率高于构成包层构件的材料的材料形成为具有矩形横截面形状的细长体。这里，芯层的横截面形状的特征在于具有矩形形状，其中横向长度是垂直方向长度的至少10倍。
