摘要

-本文研究了不同截面图案的光子晶体光纤。探讨了这些不同晶格的狄拉克点，获得了显示狄拉克谱位置的传播图，并讨论了它们在光纤导引中的应用。针对光子晶体光纤开发了一种准三维 FDTD 仿真方法，这种方法比商用三维 FDTD 仿真软件更简单、更高效。然后将该方法应用于[Fiber guiding at the Dirac frequency beyond photonic bandgaps, Light Sci.4 (2015) e304.].基于光子狄拉克定位的狄拉克点导引在这些光纤上得到了验证。

Photonic crystal fibers based on Dirac point-guiding

—In this work photonic crystal fibers of different cross-sectional patterns are studied. Dirac points of these various lattices are explored, propagation diagrams showing positions of the Dirac spectrums are obtained, and their application in fiber guiding is discussed. A quasi-3D FDTD simulation method, which is simpler and more efficient than a commercial 3D FDTD simulation software, is developed for photonic crystal fiber. This method is then applied to the new photonic crystal fiber proposed in [Fiber guiding at the Dirac frequency beyond photonic bandgaps, Light Sci. & App. 4 (2015) e304.]. Dirac-point guidance, which is based on Dirac localization of photons, is verified for these fibers.

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
