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 33):
The optical waveguide system of  claim 32 , wherein the one or more waveguide locations are selected so as to enable at least 3 dB variation of an optical power of the back-scattered light by varying the one or more control signals.
