We propose a distributed Raman amplifier available for dual-order co-propagating configuration with low-relative intensity noise (RIN) transfer. The first-order and second-order pumps are composed of incoherent and coherent light sources, respectivel

We have developed a semiconductor optical amplifier (SOA) based incoherent light source for a co-propagating distributed Raman amplifier. By utilizing the incoherent light source as a 1st-order pump of the Raman amplifier, we have experimentally veri

We experimentally shows second-order forward Raman pumping scheme combined with incoherent- and coherent-light sources can achieve 1.6-dB Q-improvement of PDM-16QAM signal in WDM configuration while keeping low RIN transfer after 1,760-km standard SM

We propose a method to measure the Jones matrix of the transmission medium without violating the unitarity of the matrix. Our method consists of defining the normalized Jones matrix each time the unitarity is lost by experimental error. Numerical sim
