  • Multichannel polarization stabilization employing synchronous phase-locking methods
    Patent number: 8922772
    Abstract: A multichannel optical system including a mixing device responsive to a sample beam and a reference beam that provides an in-phase signal including the mixed sample beam and reference beam having a relative phase of 0° and a quadrature phase signal including the mixed sample beam and reference beam having a relative phase of 90°. The system also includes a photodetector responsive to the quadrature phase signal that converts the quadrature phase signal to a quadrature phase electrical signal. A polarization demultiplexer circuit receives the quadrature phase electrical signal and measures the amplitude of a unique time-dependent phase dither profile having a zero time-averaged mean and a zero time-averaged correlation to the other phase dither profiles and provides a polarization amplitude signal. A polarization controller receives the polarization amplitude signal and controls the reference beam to maximize the polarization amplitude signal.
