We present in numerical simulations the robustness of subcarrier index modulation (SIM) OFDM to combat laser phase noise. The ability of using DFB lasers with SIM-OFDM in 16-QAM CO-OFDM system with 1024-point FFT has been verified. Although SIM-OFDM has lower spectral efficiency compared to the conventional CO-OFDM system, it is a good candidate for 16-QAM CO-OFDM system with 1024-point FFT which uses a DFB laser of 1 MHz linewidth. In addition, we show the tolerance of SIM-OFDM for mitigation of fiber nonlinearities in long-haul CO-OFDM system. The simulation results show a significant penalty reduction, essentially that due to SPM.

We propose a novel IQ imbalance compensation for coherent optical OFDM. One test tone is used. The results show good imbalance tolerance improvements when large laser phase noise and a dispersive channel are considered.

The effects of fiber nonlinearity in Coherent Optical Orthogonal Frequency-Division Multiplexing (CO-OFDM) transmission, such as self-phase modulation (SPM) and cross-phase modulation (XPM), are a major concern. In this paper, we investigate the use of RF-Pilot (RFP) based nonlinearity compensation scheme in frequency domain to compensate for fiber nonlinearity in a coherent OFDM optical system. It shows that the RFP-based compensation scheme has superiority over a conventional pilot-based compensation scheme at FEC threshold.
