  ABSTRACT: 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.

  ABSTRACT: In this letter, the transverse loading characteristics of Bragg gratings in microstructured optical fibers were investigated by use of an active fiber depolarizer. Increasing transverse load shifts the Bragg wavelength to longer wavelengths; its sensitivity to transverse load decreases with increasing volume of air holes around the fiber core. Such transverse loading characteristics were found to be dependent on the fiber orientations.
