Single mode fibers
Hundreds of active fibers in stock
Since the discovery of ZBLAN glasses in 1974, Le Verre Fluoré has worked to develop a large range of single mode fluoride optical fibers, including ZrF4, InF3 and AlF3 based optical fibers, designed for mid-infrared applications.
Our single mode fluoride fibers can be separated in two main categories :
- ZFG (Zirconium ZrF4 Fluoride Glass) = fluorozirconate / ZBLAN fibers
Exhibit a high transparency from 0.3 up to 4.5 µm (see graph below) - IFG (Indium InF3 Fluoride Glass) = fluoroindate fibers
Exhibit a high transparency from 0.3 up to 5.5 µm (see graph below)
Multimode fibers
- ZFG: Typ < 20dB/km at 2.5 µm
- IFG: Typ < 20dB/km at 3.6 µm
- GeG: Typ < 150 dB/km at 2.78 μm < 400 dB/km at 2.94 μm
- ZFG: 0.32-4.3µm
- IFG: 0.335-5.3µm
- GeG: 2.78 and 2.94µm
- Transmission: design of the fiber can be adjusted depending on your operating wavelength (cut-off)
- Non linear fiber: despite similar non linear refractive index than that of silica, long lengths of fibers can be used to generate supercontinuum.
With a high rare earth solubility (Er, Ho, Tm, Dy, Pr, Yb, Nd, Ce, Sm… up to 100 000 ppm) and low phonon energy, dozens of rare earths transitions are active in fluoride glasses.
- Small core rare earth doped fluoride fibers can be used to amplifiy O-band, S-band or other wavelengths.
- Single clad and double clad rare earth doped fluoride fibers are widely used to generate mid infrared lasers, but also visible lasers.
Other specialty optical fibers such as polarization maintaining ZBLAN fibers have been developped for instrumentation.
