The F-NL-PM-750 (NKT P/N NL-PM-750) Polarization Maintaining Nonlinear Photonic Crystal Fiber is a high-index-guiding type fiber designed with a small 2.0 μm core to get a high nonlinear coefficient. The high index difference between the silica core and the air-filled microstructure enables tight mode confinement resulting in a low effective area and thereby a high nonlinear coefficient. The air-filled region also results in strong wavelength dependence in the characteristics of the fiber and is responsible for the large wave-guide dispersion possible in such fibers. The wave-guide dispersion can be used to enhance or cancel out the material dispersion in the fiber and the flexibility in terms of dispersion profile is therefore much bigger in PCFs than in standard fibers. The F-NL-PM-750 nonlinear fiber is designed with relatively small holes to be singlemode at the 750 ± 15 nm and 1260 ± 20 nm zero dispersion wavelengths. This approach has several advantages compared to multimode nonlinear fibers with large air holes. First the fibers are easier to splice to solid standard fiber due to the lower air-filling fraction. Second alignment and focusing with free-space coupling is less critical as light focused on the cladding region will not be coupled, unlike in high-air-filling fraction fibers, where light can be guided in the silica islands between the large holes.

f - nl - pm - 750(NKT P / N nl - pm - 750)非线性光子晶体光纤是一种high-index-guiding偏振保持光纤设计小2.0μm核心高非线性系数。二氧化硅核与充气微结构之间的高折射率差使得紧密模态约束导致有效面积低，从而产生高非线性系数。充满空气的区域也导致了纤维特性对波长的强烈依赖，并导致了这种纤维中可能存在的较大的波导色散。波导色散可用于增强或消除纤维中的材料色散，因此，在PCFs中，色散剖面的灵活性要比标准纤维大得多。非线性光纤f - nl - pm - 750设计相对较小的孔是单模750±15海里和零色散波长1260±20海里。与具有大空穴的多模非线性光纤相比，该方法具有许多优点。首先，由于空气填充率较低，纤维更容易与固体标准纤维结合。第二次对准和自由空间耦合的聚焦不那么关键，因为聚焦在包层区域的光线不会耦合，不像在高空气填充纤维，光可以引导在大洞之间的二氧化硅岛。标准价格是每米。
