We report a thermo-optic switching effect with a high extinction ratio of 30 dB by means of filling a fluid into air holes of a solid-core photonic crystal fiber (PCF). Such an effect can perform a turn on-off operation of the transmitted light via a small temperature adjustment of ??10??C. The switching function attributes to the absorption of the filled fluid in combination with the interaction between the core mode and the excited ??fluid rod?? modes, resulting from the thermo-optic effect of the filled fluid.

    • "Another way to find new properties of such fibers was air replacement in the microstructure by other materials such as gases [3], liquid crystals [10] [11], immersion oils [12] [13], organic mixtures [14] [15], polymers [16] and nanofluids [17- 19]. From two main types of MSFs, i.e. solid core and hollow core, fibers from the first group are more extensively investigated. "

    ABSTRACT: In this paper we have been experimentally investigated thermo-optic properties of a Co nanofluid filled mictrostructured fiber (MSF). We have prepared samples based on pure chemical compounds: cyklohexane and toluene and both of them were used as solvents for Co nanoparticles. MSF filled by cyklohexane and its mixture with Co nanoparticles worked on weakly guided regime and toluene based MSFs samples became the solid core bandgap fibers. We have measured temperature transmission spectral characteristics within the range of 18°C-80°C. Temperature sensitivity of Co nanofluid based on cyklohexane were the strongest in third telecommunication window and reached 0.12dB/°C with dynamic range of 7dB. For toluene based samples we observed bandgaps shifts from the longer to the shorter wavelengths. Temperature sensitivity of these type of samples were close to -5nm/°C.

    ABSTRACT: A half-filling technique was demonstrated to improve the bending properties of a fluid-filled photonic crystal fiber. Such a technique can realize to fill selectively a fluid into half of air holes in a PCF. The bending properties of the half-filled PCF are quite different from those of the fully-filled PCF. Distinct bending properties were observed when the half-filled PCF was bent toward different fiber orientations. Especially, the transmission spectrum of the half-filled PCF was hardly affected while the fiber was bent toward the filled-hole orientation.

    ABSTRACT: A versatile technique is demonstrated to fill selectively a fluid into desired air holes in a microstructured optical fibers (MOFs). A fan-shaped groove is carved on the fiber surface to expose selected air holes to atmosphere by a micromachining system consisting of a femtosecond IR laser and a microscope. Then a fluid is filled into the exposed air holes through the carved groove with the well-known capillarity action. Such a technique can be used to fill selectively several different types of fluid samples into desired air holes in an MOF by means of carving fan-shaped grooves on different orientations of the fiber surface.
