采用平面波展开法,通过模拟分析带隙型光子晶体光纤空气填充率和介电常数对带隙的影响,对光纤的平面内和平面外带隙特性进行了研究与讨论.
The influence of air filling fraction and cell on the band gap is investigated by plane wave expansion method, for photonic crystal fibers based on the triangular periodic structure. Accordingly, in-plane and offplane PBG of PBG-PCF are studied and analyzed in detail.
