Abstract

Performance degradation of high-order modulation and high baud-rate systems due to transmitter electrical I/Q cross-talk inherent in photonic integrated circuits is characterized. A post-compensation technique based on receiver-side DSP is proposed. The cross-talk level requirement for 64QAM 64GBaud is reduced from -30dB to -24dB.
