Abstract
Dual-order silicon Raman Amplifiers are analyzed and numerically discussed. The effect of relative intensity noise (RIN) transferred from second-order pump to signal in 1-cm long chip scale silicon Raman amplifiers is investigated. Similar to single-order silicon Raman Amplifiers, −3dB corner frequency of RIN transfer function in second-order silicon Raman Amplifiers is almost the same as that in single-order silicon Raman Amplifiers due to lack of sufficient “walk off” in short waveguide length. The noise figure of dual-order silicon Raman amplifiers is deteriorated than single-order silicon Raman Amplifiers.
