An optical semiconductor module uses a first lens and a second lens. The face of incidence of the second lens is cylindrical so that the mode field of an optical fiber can be converted to be elliptical. Consequently, the light from an optical semiconductor element is coupled efficiently to an optical fiber.

La présente invention concerne un module de semiconducteur optique utilisant une première lentille et une seconde lentille. L'angle d'incidence de la seconde lentille est cylindrique de sorte que le champ de mode d'une fibre optique puisse être converti en champ elliptique. Par conséquent, la lumière émise par un élément à semiconducteur optique est efficacement couplée à une fibre optique.
