Abstract :
We present a report on the experimental validation of double-pass discrete Raman amplifier based on dispersion compensating fiber and high reflection fiber Bragg grating at pump wavelength. The pump light at 1435 nm is launched in counter-directional to the incoming input signal. The double-pass direction of the signal is achieved through a fiber loop mirror constructed by a circulator. We proved that with the proposed design, it requires only 55% of the pump power to achieve the same Raman gain compared to the typical single-pass Raman amplifier.
