Abstract
An output of a light source coupled to an optical fiber is controlled by an apparatus comprising a mode stripper for stripping a first part of the optical signal from the cladding of the optical fiber, means for bending the optical fiber and withdrawing a second part of the optical signal from a core of the fiber downstream from the stripper, means for detecting the second part of the optical signal, and feedback means for using the detected second signal part to control an output of the light source to better linearize an amount of power injected into the fiber.
