The PDL(polarization dependent loss) of the VAF(variable attenuation filters) was calculated,and the influence on the PDL due to the coating technology was also analyzed,then the method to reduce PDL was presented.

We first briefly introduce the commonly used calculation and analysis methods for Polarization-Dependent Losses(PDL) and conduct the analysis and calculation of the PDL of optical devices by using the Polarization Analysis function of ZEMAX.

Using the Multiple Important Sampling(MIS) technique,the performances of 10 Gbit/s optical communication systems affected jointly by Polarization-Mode Dispersion(PMD) and Polarization Dependent Loss(PDL) are simulated under different initial pulse chirps and duty cycles.

The effects of polarization-mode dispersion and polarization-dependent loss on 10 Gbps systems with two modulation formats are investigated using multiple importance sampling.

On the basis of the theory of wave-optics, a theoretical model used to compute the polarization-dependent loss of a polarization-independent isolator is established.

The magnetic field sensitivity of polarization-dependent loss for left-/right-handed circularly polarized light in sectional magneto-optic fiber Bragg gratings(MFBGs) is analyzed by using the piecewise-uniform grating model and it is shown that the central section of uniform MFBGs is most sensitive to magnetic field.

Simulation showed the delay of a chirped Gaussian pulse depends not only on polarization-dependent loss(PDL),but also on the chirp of the pulse itself.
