Polarization properties of polymer-based photonic crystal fibers

Abstract

Abstract-Selectively filled photonic crystal fibers with polydimethylsiloxane (PDMS), a silicon-type material, have been studied. It has been demonstrated that polarization properties of these hybrid devices change and so do the properties of guided light in relation with temperature, finding that the state of polarization (SOP) changes with an increasing temperature but remains constant for a wide spectrum of wavelengths for a determinate temperature.

Hybrid liquid crystal–photonic crystal fiber tunable interferometer

“…Depending on the relative refractive indices, PCFs may guide the propagating light by total internal reflection (TIR) as in standard fibers or by photonic band‐gap where only certain ranges of wavelengths are guided. The guiding properties of the PCF are altered by infiltrating the cladding holes with liquids or gases . Moreover, an active device may be obtained out of a passive PCF by filling these holes with active optic materials like liquid crystals (LCs) .…”

Thermally tunable polarization by nanoparticle plasmonic resonance in photonic crystal fibers

“…Collapsing the small holes (by fiber splicing, for example), the large holes can be easily infiltrated with liquids (or precured PDMS) [31]. Filling high viscosity liquids like PDMS occasionally requires applying positive pressure after collapsing the smaller holes to complete filling.…”

“…In this work, localized SPRs in silver nanoparticles (AgNP) have been theoretically studied eventually aiming to the simplicity of the mixture fabrication [30] and the filling process [31].NPs are commercial as well as PDMS, thus no technological effort to produce complex structures is necessary.…”
