For specific needs such as mode scrambling, we design and draw multimode fibers with special core shapes such as hexagonal, octagonal, etc…
Those fibers were drawn from ZFG (Zirconium ZrF4 Fluoride Glass) = fluorozirconate fibers
Exhibit a high transparency in UV, visible and mid-infrared from 0.3 up to 4.5µm (see graph below) :
- 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
Find below a short description of our standard ZFG octogonal core multimode fibers for mode scrambling:
∅core (µm) | ∅cladding (µm) | Numerical aperture | Reference |
|---|---|---|---|
105 | 150 | 0.20 | ZFG OCT (0.20) 105/150 |
90 | 150 | 0.15 | ZFG OCT (0.15) 90/150 |
This mode scrambling fibers were developed for the SPIRou and SPIP projects and are now integrated in a near infrared spectropolarimeter and a high precision velocimeter.
