Passive Fibers
ZFG Polarization maintaining
In order to maintain linear polarization during proropation throught the fiber, LVF has developed special PM fibers. The linear polarization during propagation is obtained thanks to two air-gaps (see fiber section image).
LVF delivers a standard ZFG polarization maintaining fiber.
∅core (µm) | ∅cladding (µm) | Numerical aperture | Cut-off wavelength (µm) | Beat length @2.8 µm (mm) | Reference |
|---|---|---|---|---|---|
6.5 | 125 | 0.23 | 1.95 | ≈ 20 | ZFG PM [1.95] 6.5/125 |
This polarization maintaining fiber was developped for the GRAVITY project and is now integrated system including a delay line and a polarization rotator.
