摘要：

An equiangular spiral (ES) photonic crystal fiber (PCF) design in tellurite glass has been presented. The structure parameters have been tailored for zero dispersion wavelength (ZDW) at lambda(ZDW)= 1570 nm. The fiber structure has high nonlinearity (gamma = 2000 w(-1) Km(-1)) at 1550 nm wavelength with very low and flat dispersion -0.152 [ps/(nmxkm)]. We have generated supercontinuum using only 2 mm length of tellurite ES PCF with low input pulse energy of 200 pJ by pumping at 1550 nm. The proposed fiber may be a suitable candidate for nonlinear applications.
