Impact of preform fabrication and fiber draw on the optical Properties of microstructured fibers

摘要

We report recent results concerning the loss and transmission properties of both index guiding and photonic band gap microstructured fibers generated via a sol-gel method. The loss for an index guiding microstructed fiber at 1550 nm is 2 dB/km and shows an attenuation of 6 dB/km at 1385 nm, displaying the lowest level of hydroxyl in any microstructured fiber. Our results are compared to other recently published results.
