Abstract
An optically coupled device and an optical module including the optically coupled device are provided that can appropriately and efficiently perform position measurement of an optical surface, and allow a product having superior overall efficiency to be stably manufactured at a low cost. An optically coupled device main body 15 is formed having a shape that allows both first lens surface 5 and second lens surface 8 to be viewed simultaneously from a surface normal direction of at least one of a first surface portion 2a and a second surface portion 3a.

An optically coupled device to which a photoelectric conversion device on which a photoelectric conversion element that emits or receives light is formed and a multi-mode optical fiber can be attached, and that can optically couple the photoelectric conversion element and an end surface of the optical fiber, the optically coupled device comprising:
- a first lens surface formed on a first surface portion of an end surface on the photoelectric conversion device side of an optically coupled device main body, the first surface portion facing the photoelectric conversion element when the photoelectric conversion device is attached, the first lens surface forming an optical path connecting the photoelectric conversion element and an end surface of the optical fiber;
- a second lens surface formed on a second surface portion of an end surface on the optical fiber side of an optically coupled device main body, the second surface portion facing the end surface of the optical fiber when the optical fiber is attached, the second lens surface forming an optical path connecting the photoelectric conversion element and the end surface of the optical fiber;
- wherein, the optically coupled device main body is formed having a shape in which the end surface on the photoelectric conversion device side and the end surface on the optical fiber side are adjacent to each other, and the first surface portion and the second surface portion are perpendicular to each other, and formed having a shape allowing both the first lens surface and the second lens surface to be viewed simultaneously from a surface normal direction of at least one of the first surface portion and the second surface portion.
