摘要
从光子晶体光纤(PCF)的包层基模理论出发,采用全矢量有效折射率方法对在光纤通信窗口1.55μm附近具有宽带平坦色散特性的PCF进行了数值模拟。将PCF的总色散分为材料色散和波导色散2部分进行计算,并利用波导色散的归一化性质即可设计在1.55μm波段具有×102 甚至数×102 nm带宽的宽带平坦正常、反常或零色散特性的PCF。
Photonic crystal fibers, also referred to as holey fibers or microstructured optical fibers, are the generic term for a new class of all silica optical fibers whose cladding typically comprises a hexagonal array of air holes running along the entire length. From the theory of fundamental space-filling mode of photonic crystal fibers (PCFs), the PCFs with broadband flattened dispersion property around the telecommunication window (around 1.55 μm are investigated by a full vectorial effective index method in this paper. The total dispersion of photonic crystal fibers is obtained by summing up material dispersion and waveguide dispersion. Using the normalized property of waveguide dispersion, the photonic crystal fibers (PCFs) with more than one hundred or even several hundred nanometers broadband ultra-flattened normal, anomalous, and zero dispersion property around 1.55 μm coere designed.
