Abstract
A method for resetting a polarization controller includes determining that the phase magnitude is associated with a first range of phase angles and generating a first control signal having a first characteristic if the phase magnitude is increasing, and generating the first control signal having a second characteristic if the phase magnitude is decreasing. The phase magnitude associated with a second range of phase angles is determined. The first control signal having the second characteristic is generated if the phase magnitude is increasing. The first control signal having the first characteristic is generated if the phase magnitude is decreasing.
