The waveguide (204) includes an equal-width first waveguide (301), an equal-width second waveguide (302), and a third waveguide (303). A first end of the third waveguide (303) is connected to a first end of the first waveguide (301) and a first end of the second waveguide (302), and the first waveguide (301), the second waveguide (302), and the third waveguide (303) form a Y shape. Along a first direction of the principal axis, a width of the third waveguide (303) gradually increases, and a distance, in a second direction, between the first waveguide (301) and the second waveguide (302) gradually decreases. The spotsize converter (200) can be used to implement spot size conversion between an optical fiber and an optical waveguide, and a coupling loss between the optical fiber and the optical waveguide can be reduced by using the spotsize converter (200).
