The use of fiber cladding modes broadens the range of possible applications of fiber optical sensors. The cladding mode resonance excited by fiber Bragg gratings, in particular tilted Bragg gratings, is discussed. The most commonly used method of excitation of cladding modes based on long-period fiber gratings is considered. We describe applications of long-period fiber gratings as sensors of strain, temperature, refractive index, chemical composition, twist, etc. Propagation of cladding modes in fiber interferometers and cascaded long-period fiber gratings is analyzed.","PeriodicalId":309922,"journal":{"name":"International Conference on Coherent and Nonlinear Optics","volume":"270 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115596289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two methods for Nd3+ ions concentration measurements in the crystals are used. The first one - X-ray fluorescence analysis (XRFA) - is used to establish the absolute concentration of impurity ions, and the second - optical absorption spectroscopy (OAS) - allows to estimate not absolute, but relative impurity concentration. By comparison of the results given by both methods the integral cross-sections of 4I9/2-2G7/2 transitions of Nd3+ ions doped in these crystals were estimated. Thus, the standard samples, allowing to establish the absolute Nd3+ ions concentration in LiLuxY 1-x F4(x=0- 1) crystals by means of OAS-method, were created.","PeriodicalId":309922,"journal":{"name":"International Conference on Coherent and Nonlinear Optics","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126280482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The scheme offered is based on process of four-partite state generation in coupled parametric interactions realizing in an aperiodic nonlinear photonic crystal. The coupled nonlinear optical process consists of one parametric down-conversion process which is followed by two up-conversion ones. We study nonclassical properties of the generated fields by analyzing the EPR correlations for different pairs of modes and carry out the comparison of the EPR correlations of the input and images output images and also calculate fidelity of the teleportation exploiting the covariance matrices of the images. We take into account the difference of spatial frequency bandwidths of the entangled images and fields generated in the coupled process. It has been established that under certain parameters of the scheme one can be obtain rather high fidelity of the teleportation and good preservation of the quantum correlations of the input images for all details of the images.","PeriodicalId":309922,"journal":{"name":"International Conference on Coherent and Nonlinear Optics","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115937789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This effect opens an opportunity to design new tools for observation of the nanometer scale objects without destruction. The general picture can be considered in the approximation of the steady-state wave function. The outgoing wave is described by the amplitude slowly varying along the trajectory. Quantum formulation of photodetachment of a negative ion as the steady-state process is equivalent the inhomogeneous Schrödinger equation. Its solution can be expressed in terms of the Green's function. The exact expression for the Green's three-dimensional function is known in two cases: homogeneous electric field and the Coulomb field. The detailed picture for distribution of photocurrent in a homogeneous field demonstrates the advantages of the quantum theory approach. We found the repulsive Coulomb field is more effective for extension the area of the interference pattern at a small distance from an ion.","PeriodicalId":309922,"journal":{"name":"International Conference on Coherent and Nonlinear Optics","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130468580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
