Abstract
Optical couplers for injecting an optical control signal onto an optical fiber include a micro-ring resonator that is coupled to the optical fiber, an optical transmission path and a modulator that is configured to vary a distance between the optical transmission path and the micro-ring resonator in order to selectively couple light from the optical transmission path onto the micro-ring resonator.
