This type of amplifiers is highly appreciated due to their applications in all-optical signal processing. Signal amplification can be achieved using single-pump or dual-pump pumping schemes. Dual-pump FOPAs provide smoother gain over wider bandwidth than single-pump FOPAs, but it is harder to maintain high performance of dual-pump FOPAs due to the stimulated Raman scattering (SRS) induced energy transfer from one pump to another. In this paper the authors investigate the performance of a dual-pump FOPA under the influence of SRS in order to ensure higher gain using as low pump power as possible in a 4-channel 40 Gbps wavelength-division multiplexed transmission system.</p> <p>DOI: <a href="http://dx.doi.org/10.5755/j01.eie.23.6.19699">http://dx.doi.org/10.5755/j01.eie.23.6.19699</a></p>}, number={6}, journal={Elektronika ir Elektrotechnika}, author={Olonkins, Sergejs and Bickovs, Vladislavs and Salgals, Toms and Bobrovs, Vjaceslavs and Ivanovs, Girts}, year={2017}, month={Dec.}, pages={85-89} }
