Two-pump optical parametric amplification in the S-band using a tellurite microstructured optical fiber

In this paper, two-pump optical parametric amplification (OPA) of S-band signals based on a tellurite microstructured optical fiber (MOF) is proposed and simulated. Since the length required to obtain high parametric gain reduces dramatically since, tellurite-based MOFs possess higher nonlinear parameters than those of standard silica fibers. Simulation results showing a wide and flat band with a very high gain over the S-band region which implies that tellurite-based fiber OPAs are comparable with the conventional thulium-doped fiber amplifiers. This unique feature may be used in diverse fields including satellite communication, microwave, and wireless network devices.
