Abstract:
Back scattering in an optical waveguide at an operating wavelength is controlled by adjusting an optical phase of light propagating in the waveguide at one or more locations along the waveguide. A portion of the back scattered light is tapped off near an input port and coupled into a photodetector. A controller detects changes in the photodetector signal and adjusts an optical phase tuner configured to control the optical phase of light in the waveguide at the selected location or locations. The optical phase tuner may be configured to vary the refractive index of at least a portion of the waveguide.

Claim (Index 38):
The optical waveguide system of  claim 37  wherein at least one of the first waveguide section and the second waveguide section comprises an optical waveguide device selected from a list consisting of: a Mach-Zehnder waveguide interferometer, an optical waveguide modulator, a micro-ring resonator, a directional coupler, a multi-mode coupler, an array waveguide grating, an optical polarizer, an optical filter.
