Opto-mechanical Response Of A Suspended-slab-core Optical Fiber

In this paper we report the numerical evaluation of the opto-mechanical response of a microstructured optical fiber design when submitted to hydrostatic pressure. The fiber was built in silica and is composed of two large holes surrounding a wide thin flat region (suspended-slab-core) that is able to support optical propagating modes. A full-vector finite element program was used to the stress-optical analysis. The opto-mechanical sensitivity of such fiber was evaluated under two schemes of applied hydrostatic pressure. © American Institute of Physics.1055141144Bjarklev, A., Broeng, J., Bjarklev, A.S., (2003) Photonic Crystal Fibres, , Boston, Kluwer Academic PublishersJoly, N.Y., Birks, T.A., Yulin, A., Knight, J.C., St. Russel, P.J., (2005) Optics Letters, 30 (18), pp. 2469-2471Szpulak, M., Martynkien, T., Urbanczyk, W., (2004) Applied Optics, 43 (24), pp. 4739-4744Schreiber, T., Schultz, O., Schmidt, O., Röser, F., Limpert, J., Tünnermann, A., (2005) Optics Express, 13 (10), pp. 3637-3646MacPherson, W.N., Rigg, E.J., Jones, J.D.C., Kumar, V.V.R.K., Knight, J.C., St, P., Russel, J., (2005) IEEE J.

Hybrid Photonic Crystal Fiber Sensing Of High Hydrostatic Pressure

The opto-mechanical response of Hybrid Photonic Crystal Fiber (HPCF) with Ge-doped inclusions is numerically modeled for high hydrostatic pressure sensing purpose. A typical photonic crystal fiber (PCF) consists of a silica solidcore and a cladding with a hexagonal lattice of air-holes. The HPCF is similar to the regular PCF, but a horizontal line of air-holes is substituted by solid high index rods of Ge-doped silica. The optical guidance in HPCFs is supported combining two physical effects: the modified total internal reflection and the photonic bandgap. In such fibers, the Gedoped inclusions induce residual birefringence. In our analysis, we evaluate the susceptibility of the phase modal birefringence and group birefringence to hydrostatic pressure. The analyses were performed at a photonic bandgap with central wavelength near to 1350 nm. The polarimetric pressure sensitivity is about 10 rad/MPa x m at λ = 1175 nm. © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).7753Oz Optics,Simbol Test Systems, Inc.,FISO Technologies, Inc.,CMC Microsystems Corporation,Innovative Economy: National Strategic Reference FrameworkCerqueira, A.S., Hybrid photonic crystal fiber (2006) Opt.

Multiphysics Analysis Of An All-photonic Crystal Fiber Device

A multiphysics analysis of an all-fiber device based on photonic crystal fiber is reported. The device is a solid-core high-birefringent photonic crystal fiber with two integrated electrodes at the cladding region. A finite clement code was used to perform an electro-thermo-mechanical-opto coupled analysis. The device operates applying an electrical current on the integrated electrodes that causes heating by Joule effect and, consequently, its thermal expansion which squeezes the fiber microstructure. The results demonstrate the possibility of actively tuning the modal birefringence with electrical current. ©2009IEEE.800803Chesini, G., Cristiano, M., Cordeiro, B., Christiano, J., De Matos, S., Fokine, M., Isabel, C., Knight, J.C., All-fiber devices based on photonic crystal fibers with integrated electrodes (2009) Optics Express, 17 (3), pp. 1660-1665. , FebruaryFokine, M., Nilsson, L.E., Claesson, A., Berlemont, D., Kjellberg, L., Krummenacher, L., Margulis, W., Integrated fiber Mach-Zehnder interferometer for electro-optic switching (2002) Opt.

Minimalist optical fiber design: capillary-like fibers

Microstructured optical fibers with ultra-simplified designs are investigated. Guiding mechanism can be achieved in an embedded or surface germanium-doped core or in the hollow part of capillaries. Fiber wall thickness and/or stress induced birefringence can be modified with external stimuli. Results showing this interesting platform for sensing of parameters such as pressure, temperature, refractive index and directional curvature will be presented.CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPSem informação2014/50632-6SBFoton International Optics and Photonics Conference2018-10-08Campinas, S

Strong Power Transfer Between Photonic Bandgaps Of Hybrid Photonic Crystal Fibers

This work reports the strong nonlinear power transfer between two adjacent photonic bandgaps of hybrid photonic crystal fibers. The nonlinear phenomenon originates from the generation of a resonant radiation in a particular bandgap, which is ensured by launching a femtosecond pulse near the zero-dispersion wavelength of a lower-order adjacent bandgap, where its correspondent soliton is formed. A theoretical description based on fiber dispersion properties and phase-matching conditions is presented to contribute to the interpretation and understanding of the highly efficient energy transference. Furthermore, various experimental results are reported, including the resonant radiation that peaks at 8.5 dB above that of the initial pulse, which represents a significant enhancement in the nonlinear efficiency compared to previous published works in the literature.223641Arismar Cerqueira, S., Jr., Recent progress and novel applications of photonic crystal fibers (2010) Rep.
