A novel birefringent photonic crystal fiber (BPCF) which is symmetrically filled with magnetic fluid (MF) into the transverse air-holes was presented firstly. The magnetically induced tuning properties of the BPCF filled MF were simulated and analyzed by the full-vector finite element method with a perfectly matched layer. The mode field distributions, polarization properties and the confinement loss of the BPCF filled MF were figured out and simulated. The results show that the properties of the BPCF filled MF can be tuned by adjusting the magnetic field and the duty ratio d/Λ. The phase birefringence B decreases with the increase of magnetic field H under the condition of the same duty ratio d/Λ. The B increases with the increase of duty ratio d/Λ under the condition of the same magnetic field H. When the wavelength λ=1550nm, the duty ratio d/Λ=0.9, the phase birefringence B decreases from 0.005575 to 0.004472 with the H changing from 20Oe to 300Oe. The birefringence effect is ten times higher than the general fiber and there is a fairly good linearity..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
