Abstract
We suppressed fiber fuse propagation in hole-assisted fiber (HAF) and
photonic crystal fiber (PCF) with input powers above 14 W at 1480 and 1550
nm. This result indicates that the threshold power of fiber fuse propagation
in HAF and PCF can be at least 10 times larger than that in conventional
single-mode fiber (SMF) in the optical communication band. We also observed
the dynamics of fiber fuse termination at a splice point between a test
fiber (HAF or PCF) and a conventional fiber (SMF or dispersion-shifted fiber
(DSF)). Our experimental results show that air holes in HAF and PCF play an
important role in suppressing fiber fuse propagation.
