Phase noise tolerant inter-carrier-interference cancellation for WDM superchannels with sub-Nyquist channel spacing

We propose and demonstrate a novel multi-input multi-output (MIMO) equalization based inter-carrier-interference (ICI) cancellation approach employing constant modulus algorithm (CMA) for supperchanels with sub-Nyquist channel spacing, where optical combs are used as optical sources. Compared with t...
