Polarization characteristics of highly birefringent photonic crystal fiber with squeezed lattice

We fabricated the highly birefringent photonic crystal fibe with squeezed lattice. The polarization dependent loss (PDL), differential group delay (DGD) and modal birefringence of fabricated fiber at 1550nm were measured to be 0.11dB, 2.18ps and 2.29×10 −4 , respectively.
