Research on Dispersion Profiles of Liquid-core Polarization-maintaining Fiber

The researches on dispersion profiles are prominent for nonlinear optics, optical communication and spectroscopy. A highly birefringent, low-loss fiber is designed in this article by introducing a double elliptical air hole in the x-direction. Furthermore, the influence of birefringence and dispersion with the structure parameters and wavelength have been demonstrated. To realize the application in nonlinear optics, we have filled the fiber core with SC2 and the effective mode area and nonlinear coefficient have been calculated to verify the performance in nonlinear applications. We consider that the proposed bias-preserving fiber is highly forward-looking in the design of high birefringence fiber and dispersion-compensating fiber when applicated in nonlinear fiber optics and optical communications.
