Lightera Highly-Non-Linear Optical Fiber (HNLF) combines a high non-linear coefficient with a small dispersion slope. The fiber design includes a high delta core, doped with GeO2, surrounded by a deeply depressed ring doped with fluorine.
HNLF is available in five versions: HNLF Standard with a dispersion slope of 0.019 ps/(nm2·km), HNLF Zero-slope with a dispersion slope of 0.006 ps/(nm2·km), HNLF-PM which is polarization maintaining, HNLF Al-Doped with an aluminum doped core for increased SBS threshold, and HNLF-SPINE (Stable Phase-matching for Improved Nonlinear Efficiency) with a zero dispersion wavelength that is very stable along the fiber length. All are available with wide range dispersion values.
