The authors demonstrate the generation of a highly coherent multicarrier signal that consists of eight clearly resolved 10.7-GHz coherent sidebands generated within 3 dB of the spectral envelope peak and with an extinction ratio in excess of 45 dB by gain switching a discrete mode (DM) laser. The generated spectral comb displays a corresponding picosecond pulse train at a repetition rate of 10.7 GHz...
We investigate the statistics of the gain fluctuations of a Raman fiber amplifier pumped with a temporally incoherent pump. We present a simple theory whose predictions are in good agreement with our numerical and experimental results.
We present an experimental investigation into the statistics of the gain fluctuations of a fiber optical parametric amplifier pumped with a temporally incoherent pump. These statistics are shown to be a strong function of signal detuning.
We report on the performance of a fiber optical parametric amplifier pumped with a temporally-incoherent pump. Parametric gain coefficients seven times higher than that of a coherently pumped amplifier are demonstrated.
