Abstract

Several 7 cell core hollow-core photonic crystal fibers with bandgaps in the spectral range of 1.4 microm to 2.3 microm have been fabricated. The transmission loss follows the approximately lambda(-3) dependency previously reported, with a minimum measured loss of 9.5 dB/km at 1.99 microm. One fiber with a transmission loss of 26 dB/km at 2.3 microm is reported, which is significantly lower than the transmission loss of solid silica fibers at this wavelength.

摘要

已经制造出了几种在1.4微米至2.3微米光谱范围内具有带隙的7芯空心光子晶体光纤。传输损耗遵循先前报道的近似λ⁻³依赖性，在1.99微米处测得的最小损耗为9.5 dB/km。报道了一种在2.3微米处传输损耗为26 dB/km的光纤，这明显低于该波长下实心石英光纤的传输损耗。
