Abstract
Techniques relating to optical communications are illustrated. In an example, a system for optical communications includes a laser emitting device including an emission surface for emission of a laser beam. An optical waveguide may be optically coupled to the laser emitting device to receive the laser beam from the laser emitting device. A fault photo-detector surrounds the emission surface. The fault photo-detector is to detect a portion of the laser beam accidentally back-reflected towards the laser emitting device.
