Abstract
A device includes a first lens), a second lens, and an adjustment platform. The first lens is arranged between a first end surface and a second end surface, and enlarges the mode field diameter of light that is guided through a first optical waveguide and is emitted from the first end surface. The second lens is arranged between the first lens and a second end surface, and collects light that has passed through the first lens. The first lens is mounted on the adjustment platform. The distance between the optical axis of the first optical waveguide and the principal point of the first lens is adjusted on a plane orthogonal to the optical axis of the first optical waveguide using the adjustment platform.
