Abstract
An optical communication device includes a light source that emits a light beam and an optical fiber having a core and a cladding. The optical fiber has a light entrance face having a core region and a cladding region. The light beam emitted by the light source is converged by a converging lens on the core region and is transmitted through the optical fiber. The entrance face is configured to generate a light intensity distribution in light reflected by the light entrance face depending on a position where the light beam is incident on the entrance face, a converging lens arranged between the light source and the optical fiber.
