The Judd-Ofelt (JO) intensity parameters (Ωt), the spontaneous emission probabilities, the branching ratios and the radiative lifetimes for each observed Er3+-ion levels were determined. The stimulated emission cross section, the fluorescence full width at half maximum (FWHM), Δλeff, the Δλeff x σe factor, and the gain spectra of the main Er3+-ion lasing emission (4I13/2→4I15/2) are obtained after exciting the glass sample at 532 nm (4I15/2 →4S3/2 ). The absorption cross section of the 4I15/2→4I13/2 transition of the Er3+-ions was also obtained from absorption spectrum of the new glass. The results are compared with those reported for other Er3+-doped oxide glasses pumped at various excitation wavelengths, indicating the new Er3+- doped boro-tellurite glass has potential properties as an optical amplifier in the C-telecommunication window (1.53 μm) and a IR tunable laser. Additionally a radiative energy transfer from the glass host to the Er3+-ions was observed at 520 nm by exciting the glass sample at 466 nm into the Er3+-ion dark region.","PeriodicalId":359625,"journal":{"name":"Symposium on Optics in Industry","volume":"115 19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126372218","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}

Anatomically, the main signs of keratoconus are thinning of the cornea in its central or paracentral region, usually accompanied by an increase in this part of a high irregular astigmatism, with a consequent loss of vision. Its diagnosis requires a thorough study including the family history, a complete ophthalmologic examination and imaging studies. This diagnosis allows classifying the type of keratoconus, which allow determining options of management, with what it is possible to establish a visual prognosis of each eye. One of the indicators that help in the diagnosis of keratoconus is an inherited familiar propensity. The literature reports an incidence of keratoconus of 11%1 in first-degree relatives of patients with keratoconus. Results suggest an ethnic dependence, which implies that the knowledge of the tendency of keratoconus in the Mexican population is important. In this work, we present the preliminary results of the study realized to a group of relatives of patients who underwent corneal transplant by advanced keratoconus using Orbscan II topographic diagnosis, to determine the predisposition to Keratoconus in this group.e","PeriodicalId":359625,"journal":{"name":"Symposium on Optics in Industry","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115921542","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}

We present the concept of a lab-on-a-chip for the next generation optoelectronics and biophotonic industry including novel nanoscale material systems for lasers and detectors. Using principles such as plasmonics and near-field optics highly efficient nano-photonic lasers or modulators can be realized. The light source can be tuned from the UV to the visible range using ion implantation of noble metal such as Ag or Au in Silicon or silica. The presence of Ag or Ag nanoparticles can result in a significant enhancement of the light emission in the UV, green or red wavelength regime. Novel molecular electronics materials has been used to design olegonucleotide based photodetectors on transparent substrates for the detection of analytes in an all-optical system. Either a transparent GaN semiconductor or glass can be used as an substrate. Hybrid photonic crystal based microfluidic channels synthesized using hydrogel material can be optimized to control the flow of fluid using light.

Traditionally, arrangement with dual collimated illumination to topography measurement is used. In this case, the object analysis is limited to the size of optical collimating lens. In the case of large objects, an optical system with divergent illumination can be used. It is known that displacement fields and the phase are related by the sensitivity vector. At once, to compute the sensitivity vector, illumination sources position and superficial shape need to be considered. The last condition becomes an impediment to surface contouring. In a published work1, a simple iterative algorithm based on the Gauss-Seidel technique is presented to compute contouring measurement. In the present work, the uncertainty associated to the measurement of the topography is calculated by using the Monte Carlo method.","PeriodicalId":359625,"journal":{"name":"Symposium on Optics in Industry","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126874878","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}

Gratings were generated with Matlab® software and made with various models of laser and inkjet printers. A study of the profile gratings that depend on the symmetry in the sample was included, gratings were placed in the entrance pupil of a positive lens (illuminated by a collimated plane wave) to observe their Fourier transforms. It was found that diffraction patterns of various types of quasi-sinusoidal and quasi-triangular profiles were very close to that of sinusoidal gratings. Gradual change in the size of printed ink spots was observed in more detail through a magnification of 40x. Additionally, an atomic force microscope was used to measure the average superficial roughness of the impressions as to observe the behavior of the ink on the acetate.","PeriodicalId":359625,"journal":{"name":"Symposium on Optics in Industry","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124102238","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}
