DOI: 10.1016/j.yofte.2020.102255
Abstract: Abstract Imperfection of coherent receiver frontend can rapidly degrade system performance in coherent optical transmission systems. Those imperfection, including in-phase/quadrature (I/Q) gain and phase imbalance, and voltage mismatch between the output of integrated coherent receiver… read more here.
