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 40):
The optical waveguide system of  claim 21  wherein the at least one optical phase tuner comprises a plurality of tunable local phase shifters disposed at a plurality of locations along the at least one optical waveguide, wherein the controller is configured to adjust only a subset of the tunable local phase shifters in dependence on the one or more control signals.
