Direct-Detection Based Frequency-Resolved I/Q Imbalance Calibration for Coherent Optical Transmitters

We propose a method for calibrating the frequency dependent I/Q imbalance in coherent optical transmitters. We demonstrate that with our calibration, the OSNR penalty of a 58-GBaud 256-QAM signal can be reduced by 2.5 dB.
