Abstract
Phase imbalance between in-phase (I) and quadrature (Q) components of an optical communications signal causes signal degradation that can result in degraded bit-error rate performance, increased power requirements, and reduced transmission distance. The signal degradation can be expressed as a reduced signal to noise and interference ratio. The disclosed system and techniques monitor the phase imbalance between the I and Q channels and provides for adjustment of the phase of one or more of the I and Q channels to improve overall performance.
