Abstract
One or more single mode waveguide devices are fiber coupled such that signals to an optical element affect the coupling of the waveguide device to one or more modulators and to an optical fiber. The optical element or additional optical elements are controlled to adjust the coupling of the waveguide device to a modulator and to an optical fiber.
