Fluoride Fibers
Supercontinuum generation fibers
Thanks two their non linear properties, combined to their high transparency from UV up to mid-IR, fluoride fibers are widely used for supercontinuum generation:
In 2006 the first supercontinuum generation, extending from 0.8 up to 4.5µm was demonstrated from LVF ZBLAN fluoride fibers by Xia et al. [ref].
ZFG and IFG fluoride fibers are integrated in the commercial supercontinuum source Electro-MIR 4100 and Electro-MIR 4800, developed in colaboration with LEUKOS.
Our two star fibers for supercontinuum generation are:
1) ZFG SM [2.55] 8.5/125
Core/clad diameter
Cutoff wavelength
Numerical aperture
Zero Dispersion Wavelength
Non linear refractive index n2 (x 10-20 m²/W)

8.5/125 µm
2.55 µm
0.23
1.535 µm (experimental)
≈ 2.1
