Abstract
An optical amplifier may include an optical fiber to propagate a forward optical signal in a path of propagation of the optical amplifier. The optical fiber may have an input end face that is angled non-perpendicular to the path of propagation. The optical amplifier may include an optical component, in optical communication with the input end face of the optical fiber, to direct a backward optical emission away from the path of propagation.
