Product Spec Sheet


  • Polarization Extinction Ratio (PER) > 18 dB
  • Temperature Sensitivity 30x Lower than that of Other Leading Stress-Birefringent Fibers
  • Undoped Pure Silica Core and Cladding
  • Near-Gaussian Mode Profile (Ellipticity ~1.5)

NKT Photonics offers Polarization-Maintaining (PM) photonic crystal fibers that incorporate a non-circular core in combination with the large refractive index step between air and glass; this creates strong form birefringence. The result can be a shorter beat length that reduces the bend-induced coupling between polarization states compared with conventional PM fibers, and a much reduced thermal sensitivity of birefringence. The temperature coefficient of birefringence of these fibers is up to 30 times less than that of other leading stress-birefringent fibers. These fibers are sold based on the overall optical specifications and not the physical structure.
