چکیده انگلیسی
Many high-birefringence asymmetric microstructured optical fibers (MOFs) have been numerically designed and analyzed, but the fabrication of asymmetric MOF is challenging, especially those with elliptical structures. In this work, we designed, fabricated and modelled an asymmetric glass MOF in which the structure is asymmetric and the air holes are elliptical. SF57 glass was selected due to the high refraction index and low absorption in the Terahertz region. From simulations based on the finite difference (FD) method at 1060.0 μm, the polarizations of the first two modes are perpendicular to each other and the effective refraction indices are different, which lead to the birefringence of this MOF as high as 0.090. The plane-wave expansion method was used to verify the FD calculations, where both results are consistent and the difference is about 0.1%.
