“…with an "SC" connector via an FC/SC adaptor (coupling loss $ 0.3 dB). 21,22 We confirmed that the fiber fuse can be initiated in the same way as in glass fibers [1][2][3][4][12][13][14][15][16][17][18] by external stimuli such as heating, bending, or bringing the fiber output end into contact with an absorbent material. For the demonstration discussed here, we used a POF end surface polished roughly with 0.5-lm alumina powder.…”

“…The fuse properties in various glass fibers, including standard silica-based single-mode fibers (SMFs), [1][2][3][4][12][13][14] microstructured fibers, 15 fluoride fibers, 16 chalcogenide fibers, 16 erbium-doped fibers, 17 photonic crystal fibers, 18 and hole-assisted fibers, 18 are well documented. The fiber fuse is reported to be typically induced at an input optical power of one to several watts (one to several megawatts per square centimeter) and to have a propagation velocity of one to several meters per second.…”

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.

“…In fact, as the laser were input only from one side, the in-fiber longitudinal temperature gradient should be large during the forming of these cavities. Meanwhile, the interaction between the surrounding solid matters and the dispersive phase, probably including plasmas 4,13,37 , excited in this occasion was little evaluated experimentally. These unequilibrated environments makes theoretically modelling the forming of the cavities difficult.…”

“…In literature, fiber fuse for research was only produced by unmeasurable means, such as deliberately damaging the laser-on fibers via collision to metals 4,11 , immersion in metal powders 5,18 or shocking in electric arcs 10,17 . However, these complicated circumstances could include multiple mechanisms 20,21 that induced damages to fibers that triggered the fiber fuses.…”

We report an investigation of conditions for the initiation of fiber fuse (IFF), a kind of catastrophic damage that troubles all kinds of optical fibers, in silica-based optical fibers. The fibers of different chemical compositions were processed and tested in controlled conditions without mechanical damages before the IFF. For all the fibers of IFF, the same correlation between the critical temperatures and the optical powers transmitted therein was revealed for the first time. The fibers of different chemical compositions exhibited different resistances to the IFF under the threshold powers for propagation of fiber fuses. The results offered promise for predicting fiber fuses in optical fiber systems, which could facilitate avoiding catastrophic losses. They could direct the optimization of fiber production technologies for suppressing the damages, as well as open a new path towards controlled utilization of fiber fuse in in-fiber microstructure fabrication.

“…The first catastrophic fuse effect was reported in silica single-mode fibers (SMFs) in 1987 [4]. Since then, this effect has been reported in various special glass fibers, such as microstructured [5], fluoride [6], chalcogenide [6], erbium-doped [7], and photonic crystal [8] fibers. The fuse effect was first observed in polymer optical fibers (POFs) in 2014 [8], and its propagation mechanism was discussed in detail [8][9][10].…”

This Letter presents, for the first time, to the best of our knowledge, the dynamic mechanical analysis of a polymer optical fiber (POF) that was previously damaged by the catastrophic fuse effect. The variation of the fiber Young's modulus was evaluated with respect to the increase of temperature, humidity, and frequency of strain cycles. The obtained data for the fused POF are compared with the ones for the same POF without the fuse effect. The results show the feasibility of the fused POF for sensor applications, such as strain and acceleration measurement, since it presents temperature sensitivity almost two times lower in temperatures between 26°C and 90°C and Young's modulus 2.3 times lower than those obtained with the bare fiber. The Young's modulus variation with the humidity is 1.5 MPa/%RH in a humidity range of 66-96%. In addition, the fused POF presented a variation of its dynamic modulus with the frequency increase four times lower than non-fused POFs on the range of 0.01-100.00 Hz. These results pave the way for future applications of fused POFs as sensing elements.
