Abstract
An optical communication equipment includes a semiconductor laser element, an image-forming element, an optical fiber and a substrate for mounting the semiconductor laser element, the image-forming element and the optical fiber. An optical output of the semiconductor laser element is adapted to be provided to the optical fiber via the image-forming element. The image-forming element is mounted in a V-groove formed in the substrate and having a substantially “V”-shaped cross-section. A shortest distance between a light spot of the semiconductor laser element and an optical axis of the image-forming element is 1 mm at most and the image-forming element substantially satisfies the sine condition.
