“多孔”光纤的命名是因为它们布满着细微的小孔 ,并具有一定的图形。由于它们独特的光学特性 ,所以正受到人们的关注。这些特性包括巨大的波长色散及奇异的非线性效应。可是迄今为止 ,这种光纤的高传输损耗 (在 15 5 0 nm电信窗口的典型损耗达几百 d B/ km)一直阻碍着它的很多 “Porous” optical fiber is named because they are filled with tiny holes, and have a certain shape. Because of their unique optical properties, it is being people’s attention. These features include huge wavelength dispersion and singular non-linear effects. However, so far, the high transmission loss of such fibers (typical loss of several hundred d B / km at a 1560 nm telecom window) has been hindering many of them
