Abstract

We report the fabrication and characterization of the first guiding chalcogenide As(2)S(3) microstructured optical fibers (MOFs) with a suspended core. At 1.55 microm, the measured losses are approximately 0.7 dB/m or 0.35 dB/m according to the MOF core size. The fibers have been designed to present a zero dispersion wavelength (ZDW) around 2 microm. By pumping the fibers at 1.55 microm, strong spectral broadenings are obtained in both 1.8 and 45-m-long fibers by using a picosecond fiber laser.

摘要

我们报道了首例具有悬浮芯的硫族化物砷化二硫（As₂S₃）微结构光纤（MOF）的制造及特性。在1.55微米波长下，根据MOF芯尺寸，测得的损耗约为0.7分贝/米或0.35分贝/米。这些光纤被设计为在2微米左右呈现零色散波长（ZDW）。通过在1.55微米波长下泵浦光纤，使用皮秒光纤激光器在1.8米和45米长的光纤中均获得了强烈的光谱展宽。
