Abstract

We propose a tellurite core phosphate cladding composite microstructured optical fiber (MOF) with high nonlinearity and flattened dispersion for parametric amplification. To realize flattened dispersion, the structure parameters such as the tellurite core diameter, the air hole diameter and the distance between the centers of the two neighboring air holes are optimized. The ultraflat dispersion curve is obtained for tellurite core of 1.1μm, pitch of 1.2 μm and air hole diameter of 0.5 μm. In this case, the flattened dispersion with value between -4 and 0.5 ps/nm/km is obtained ranging from 1400 to 1600 nm. The nonlinear coefficient γ is as high as 2.5 m^-1W^-1 at 1.5 μm. The optical parametric gain bandwidth of nearly 200 nm can be achieved in composite tellurite/phosphate MOF with the length of 2.5 m and the pump power of 0.4 W.
