ZFG Polarization maintaining
LVF delivers a standard ZFG polarization maintaining fiber.
In that case, the linear polarization during propagation is obtained thanks to two air-gaps (see fiber section image).
Cut-off wavelength (µm)
Beat length @2.8 µm (mm)
ZFG PM [1.95] 6.5/125
This polarization maintaining fiber was developped for GRAVITY project and is now integrated system including a delay line and a polarization rotator.

Depending on your need and wavelength range of interest, fibers can be customized in order to adjust their cut-off wavelength and core diameter
