Abstract: The contribution of fiber nonlinearity to the signal gain spectrum of a fiber-optical parametric amplifier (FOPA) in presence of fiber transverse geometry variation is numerically studied in this work. This is the first time to demonstrate that the degradation of FOPA signal gain performance which is caused by fiber diameter fluctuation and zero-dispersion wavelength (ZDW) variation can be suppressed by using highly nonlinear optical fibers with short fiber length. By increasing the fiber nonlinear coefficient, the fiber length which is required to have similar value of signal gain is reduced, the signal gain bandwidth can be broadened and the spectral shape can be maintained. A tellurite microstructured optical fiber was fabricated by using a developed tellurite glass 78TeO2–5ZnO-12Li2O-5Bi2O3 mol%. The fiber outer-diameter fluctuation is less than ±0.53 % and the corresponding ZDW varies less than ±2 nm over a 1-m-long section of the fabricated fiber. The fiber nonlinear coefficien t is calculated to be 676 W-1km-1 which is 23 times larger than those values of highly nonlinear silica fibers. When the pump source is 5 W at 1557 nm, the influence of ZDW fluctuation on signal gain spectra is almost suppressed. (More)
