However, photosensitivity of standard germanosilicate fibres with a moderate concentration of germanium in the core (5 ÷ 7 mol.% GeO2) is not large and does not allow efficient writing of refractive index gratings. To increase the writing efficiency, one has to increase the germanium concentration and/or load the fibre with hydrogen [2]. Increasing the germanium concentration results in a reduction of the mode spot size and in additional losses when the fibre is spliced with a standard telecommunication fibre. Hydrogen loading complicates the grating technology and raises losses in the IR region owing to the OH-group absorption. Therefore, optimization of the grating writing technology and development of novel types of photosensitive fibres are now high on the agenda.","PeriodicalId":182420,"journal":{"name":"Bragg Gratings, Photosensitivity, and Poling in Glass Fibers and Waveguides: Applications and Fundamentals","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131005282","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}

However, the one-dimensional geometry of optical fibers limits the range of possible UV induced index structures and hence also the functionality of devices based hereon. This situation is currently changing, partly due to the large UV induced index changes available when using hydrogen loaded glass1. Large index changes permit direct writing of buried waveguide cores directly in planar silica based thin films, hence expanding the regime of UV induced index structures from one to two dimensions. The potential functionality of UV written optical devices is correspondingly increased.","PeriodicalId":182420,"journal":{"name":"Bragg Gratings, Photosensitivity, and Poling in Glass Fibers and Waveguides: Applications and Fundamentals","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125422466","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}

A striking result of this work is the drastic change in both shape and position of many of the MCD absorption bands with erbium(3+) concentration. These changes give insight into the nature of the erbium ion’s crystal field and thus its local environment.

Out-fiber diffusion of molecular hydrogen occurs when fiber is removed from hydrogen pressure. If the out-fiber diffusion after few hours at room temperature has negligible effect on the value of the initial Bragg wavelength for classical Bragg gratings (FBG), for long-period gratings (LPG) we show that this out-diffusion considerably changes the value of the initial central wavelength. Furthermore, in a reciprocal way, the in-fiber diffusion of hydrogen in LPG can induce strong shift of the central wavelength. In this paper, we present for the first time to our knowledge, both theoretical and experimental studies on the impact of hydrogen in-fiber or out-fiber diffusion on Long-Period Gratings.","PeriodicalId":182420,"journal":{"name":"Bragg Gratings, Photosensitivity, and Poling in Glass Fibers and Waveguides: Applications and Fundamentals","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123950184","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}

During poling some white material coated on the glass surface on cathode side. By ESCA analysis the white material is mainly a compound of sodium, which is the first evidence to prove the supposition that sodium captions move towards the cathode in the glass during the poling. This may help us to understand the mechanism of second-harmonic generation in the poled glass. We found the signal of second harmonics decreases with time after poling and the damping rate depends on the surrounding temperature. The signal decay in fact is the decay of the electric field and the charged particle inside glass. There is a residual signal after damping for one week, which does not change for months. The residual signal depends on the poling temperature. Thus we have to assume that there are two kinds of negative particles in the poling process in soda-lime glass.","PeriodicalId":182420,"journal":{"name":"Bragg Gratings, Photosensitivity, and Poling in Glass Fibers and Waveguides: Applications and Fundamentals","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115399485","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}
