“…The power density at which the fuse ceased, i.e., the threshold power density, was 6.61 kW/cm 2 at a propagation velocity of 21.9 mm/s. Comparing these results with those of silica SMFs (results at 1.48 μm ( 16) and the theoretical line at 1.55 μm (17)) revealed that at 1.55 μm the slope in the POF data (corresponding to the efficiency of the velocity control) was 16.8 times as steep as the silica SMF (94.1 mm•s −1 •kW −1 •cm −2 ), and the threshold power density of the POF was 186 times lower than the silica SMF (1.23 MW/cm 2 ). The minimal propagation velocity achieved at 1.55 μm was 5.7 times as low as that theoretically predicted in a silica SMF (125 mm/s).…”

Although high-transmission-capacity optical fibers are in demand, the problem of the fiber fuse phenomenon needs to be resolved to prevent the destruction of fibers. As polymer optical fibers become more prevalent, clarifying their fuse properties has become important.Here, we experimentally demonstrate a fuse propagation velocity of 21.9 mm/s, which is 1-2 orders of magnitude slower than that in standard silica fibers. The achieved threshold power density and proportionality constant between the propagation velocity and the power density are respectively 1/186 of and 16.8 times the values for silica fibers. An oscillatory continuous curve instead of periodic voids is formed after the passage of the fuse. An easy fuse termination method is presented herein, along with its potential plasma applications.

“…As higher Δ values result in smaller MFD values, it is necessary to estimate a fiber fuse threshold power. For estimations, we use the results in [5] and the estimated threshold power of fiber fuse P th reveals that about 300 mW is the possible pump power for SMF when Δ is around 3%. In this case, very long fiber is required to high gain.…”

This letter discusses a fiber design for lump Raman amplification (LRA) at 1270 nm wavelength used in passive optical networks (PON) using hybrid-Raman amplifiers, which are previously proposed. For simplicity, refractive-index profile is assumed to be step-index. Gain and optical signal noise ratio (OSNR) are calculated as a function of Δ. Considering a fiber fuse, we discuss a design of fibers used for lump Raman amplification. To realize a compact LRA, we propose a use of hole-assisted fibers (HAF) when high power laser is available.

The evolution of a fiber fuse in a single-mode optical fiber was studied theoretically. To clarify both the silica-glass densification and cavity formation, which are observed in fiber fuse propagation, we investigated a nonlinear oscillation model using the Van der Pol equation. This model was able to phenomenologically explain the densification of the core material, the formation of periodic cavities, the cavity shape, and the regularity of the cavity pattern in the core layer as a result of the relaxation oscillation and cavity compression and/or deformation. Furthermore, the production and diffusion of O 2 gas in the high-temperature core layer were described on the basis of the nonlinear oscillation model.
