Abstract
An optical communications Module for use in an optical transfer system for bidirectionally transferring a light signal through an optical fiber, the optical communications module having a light signal transmission capability, wherein the optical communications module includes: a semiconductor laser; an optical fiber coupled to a front facet of the semiconductor laser; a light splitting element for splitting light which is emitted from the front facet of the semiconductor laser and propagated within the optical fiber; and, an output-monitoring photodiode for receiving a portion of the light which has been split by the light splitting element as monitoring light, and generating a photocurrent based on the monitoring light, the photocurrent being used for controlling optical output of the semiconductor laser.
