Paper Abstract

Based on PCVD deposition process and Rod-In-Tube draw process, highly nonlinear fibers were designed and fabricated for efficient fiber nonlinearity generation. Highly nonlinear fibers employed high-concentration GeO2-doped core and fluorine-doped cladding were simulated, in which key structure parameters were investigated, such as the core diameter, core profile shape, and the b/a. The fabricated fibers successfully realized a low attenuation less than 1.30dB/km with an effective area of about 10um2 and a dispersion slope about 0.020ps/nm2/km at the operating wavelength of 1.55um. For different applications such as Raman amplifier and four-wave mixing (FWM) generation, a series of fibers were fabricated with different dispersion spectrums in the S+C+L-band. Some application experiments were also introduced, which were related to fiber properties. Our fabricated fibers achieved the maximum effective Raman gain coefficient of 5.08W-1km-1 and the nonlinear coefficient of 12W-1km-1.
