Abstract
An optical coupling system between a semiconductor laser and an optical fiber is disclosed. The system is characterized in that a medium having a refractive index greater than 1 but smaller than the refractive index of the semiconductor laser material is packed between the end surface of a distributed feedback type or distributed Bragg reflector type semiconductor laser and the end surface of an optical fiber.
