The F-AIR-20/1550 (NKT P/N HC19-1550-01) Air Guided Photonic Crystal Fiber guides light in a hollow, 20 ± 2 μm air core using the Photonic Bandgap (PBG) effect. The highly periodic structure of air holes in the cladding of the fiber creates a photonic bandgap. This means that light of frequencies within the PBG is not allowed to propagate out through the cladding and may be trapped in the core of the fiber. In contrast to index-guiding fibers, there is no requirement on the refractive index of the core region to be larger than the index of the cladding. An inherent feature of PBG-Guiding is that the fiber only guides light in a limited spectral region. This fiber operates with <0.1 dB/m attenuation at 1550 nm. Typical bandwidth is about 200 nm. Outside this region, the fiber core is anti-guiding. Extreme dispersion properties may be found in the PBG fibers, such as anomalous dispersion values in the thousands of ps/nm/km. Due to a negligible contribution from the core material (air), the total dispersion of PBG fibers is dominated by wave-guide dispersion.

F-AIR-20/1550(NKT P / N hc19 - 1550 - 01)空气引导光在空心光子晶体光纤指南,20±2μm空心使用光子带隙(PBG)的效果。纤维包层上的极具周期性的气孔结构产生了光子带隙。这意味着PBG内的频率光不允许通过包层传播，可能被困在纤维的核心。与导指数光纤相比，核心区域的折射率不需要大于包层的折射率。pbg - guide的一个固有特性是，光纤只能在有限的光谱区域内引导光线。这种纤维在1550 nm处衰减小于0.1 dB/m。典型的带宽大约是200纳米。在这个区域之外，纤维核心是反导向的。在PBG纤维中可以发现极端的色散特性，例如数千ps/nm/km的异常色散值。由于核心材料(空气)的贡献可以忽略不计，PBG纤维的总色散以波导色散为主。如需添加光纤连接器和保护外套，请联系新港技术支持。标准价格是每米。
