    For making a polarization control device with stable wideband, a novel holey birefringence fiber with stable beatlength in broadband was proposed. Some specific asymmetrical structures were introduced into the cladding by adjusting a pair of the special holes near the core, the shape and size of holes in background and the lattice pitches. The polarization beat length is not sensitive to disturbances of these asymmetric structure parameters. The polarization beat length sensitivity to wavelength was reduced effectively, and the polarization beat length sensitivity to the errors of the cladding structures was also reduced through the mutual compensation of birefringence with different trends to suppress non-linear changes. The research results showed that the operating bandwidth was up to 200 nm near the 1 550 nm wavelength window if the relative change of polarization beat length must to be less than ±4%, while the error tolerance of the clad structure geometry parameter was reached 0.1 μm. A more feasible process structure parameters was provided for the actual drawing the holey fiber with broadband stable polarization beat length.
