“…Infiltration of advanced materials into the air holes of the PCFs can potentially manipulate their optical properties creating a new category of fibers termed as hybrid PCFs [2,3]. Many hybrid devices such as switches [4], tunable devices [5], sensors [6,7] have been developed and studied by filling liquid crystal, high index fluids, metals [8] as well as other materials into the air holes by transforming an index guiding PCF into a photonic bandgap fiber (PBG) [9]. However, limited research has been so far carried out on the infiltration of PCF's holes with polymeric inclusions, conserving total internal reflection (TIR) guiding mechanism [10].…”

In this paper, we demonstrate and report a photonic crystal fiber (PCF) infiltrated with PDMS elastomer which is sensitive to external bending and temperature perturbations. Numerical simulations and experimental measurements were carried out to investigate the fundamental TIR-based guiding mechanism of the hybrid PDMS/silica PCF in terms of effective index, effective modal area and loss. Wavelength dependence of bending losses was also measured for different bend diameters as well as the temperature dependence of the fundamental guiding mode for a range of temperatures from 20°C to 75°C. Experimental measurements have shown a ~6% power recovery of the bend-induced loss for a 6-cm long PDMS-filled PCF at 4 cm bend diameter.

“…We can conclude that the problem connected with the MI could be overcome using wideband filter between the first and the second stage. We can consider, for example, a filter based on a liquid filled photonic crystal fiber filter [24].…”

We theoretically and experimentally investigate an all optical switch based on stimulated Raman scattering in optical fibers. The experimental setup consists of a Raman circuit of two stages connected in series through a bandpass filter. In the first stage, we have a saturated amplifier, in this stage the pump pulses are saturated when pump and signal are launched to the input or the pump pulses remain without saturation when pump only is launched at the input. The second stage works as the Raman amplifier; for this stage amplification is directly dependent on the pump power entering from the first stage. For the case when pump pulse only is launched at the input pass to the second stage without saturation and amplifies the signal entering in the second stage, very intense signal pulses appear at the output of this stage. For the case when both pump and signal pulses are launched to the input, the pump pulse is saturated in the first stage and the filter rejected the amplified signal, so that only low power pump enters the second stage and consequently no signal pulses appear at the output. We show that the contrast can be improved when using fibers with normal and anomalous dispersion connected in series in the first stage. The best contrast (the ratio of energies) obtained was 15 dB at 6 W pump peak power.

“…For instance, devices based on fiber Bragg gratings [14] and interference effects [15][16][17] enable RI sensing at sufficiently high sensitivity levels but suffer from rather limited spectral bandwidths. Other approaches rely on monitoring the transmission bands of complex liquid-filled photonic bandgap fibers [18,19] or other microstructured fibers [20]. Although the mentioned approaches work in principle, they require complex fiber designs, sometimes extensive post-processing and precise knowledge about the respective microstructure, which demand extensive numerical calculations using commercial finite element solvers to correlate the measured results with simulations.…”

Monolithic optofluidic mode coupler for broadband thermo- and piezo-optical characterization of liquids

et al. 2017

We present a monolithic fiber device that enables investigation of the thermo- and piezo-optical properties of liquids using straightforward broadband transmission measurements. The device is a directional mode coupler consisting of a multi-mode liquid core and a single-mode glass core with pronounced coupling resonances whose wavelength strongly depend on the operation temperature. We demonstrated the functionality and flexibility of our device for carbon disulfide, extending the current knowledge of the thermo-optic coefficient by 200 nm at 20 °C and uniquely for high temperatures. Moreover, our device allows measuring the piezo-optic coefficient of carbon disulfide, confirming results first obtained by Röntgen in 1891. Finally, we applied our approach to obtain the dispersion of the thermo-optic coefficients of benzene and tetrachloroethylene between 450 and 800 nm, whereas no data was available for the latter so far.
