The Δn of 3.2 × 10-3 was observed for a hydrogentreated (150 atm, 2 weeks, room temperature) sample after a KrF laser irradiation (25 Hz, 0.5 J/cm2/pulse, 27 kJ/cm2), while the Δn obtained for a non-treated sample is less than 10−4. The depth profile of the Δn for the hydrogen-treated sample is limited by the distribution in the hydrogen concentration inside the sample, while it is determined by the attenuation of the ultraviolet light for the non-treated sample. Ultraviolet (UV) optical absorption measurements show that the decrease at a 5.1 eV band and the increase at ~6 eV are stronger in the hydrogen treated sample than in the non-treated one. Correlation between the observed refractive index change and UV absorption change will be discussed. Also, the role of hydrogen on the enhanced photosensitivity will be discussed.","PeriodicalId":182420,"journal":{"name":"Bragg Gratings, Photosensitivity, and Poling in Glass Fibers and Waveguides: Applications and Fundamentals","volume":"14 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":"127766373","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}

It is generally well accepted that the nonlinearity in thermally poled silica is confined to a thin (1-15 μm) layer on the glass sample that was exposed to the anode side during poling. However, reports differ markedly as to the shape (exponential [1], or Gaussian [2]) and thickness (a few to 10 μm and even 700 μm) [1-3] of this nonlinear region. In practical waveguide devices, a precise knowledge of these parameters is critical to understand and maximize the spatial overlap between this region and the optical mode. Yet to date, no standard method is available to measure these quantities reliably. Earlier, we made initial measurements of the nonlinearity using a prism pair [4]. Difficulties with the homogeneity of the poled region limited the maximum angle that could be explored, and a profile could not be definitively inferred. In this paper we describe 1) improvements in this prism-assisted Maker fringe technique and 2) a theoretical analysis that permits the first absolute measurement of the nonlinearity profile in poled silica.","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":"130119888","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}

Filters with flat passbands, which can separate channels spaced by 100 GHz, are needed to allow many devices to be concatenated without decreasing the available channel bandwidth significantly. A Mach- Zehnder Interferometer (MZI) with UV-induced gratings realized using planar waveguides [1] is an attractive architecture for creating an add-drop filter (see Fig. 1a). To increase the number of devices which can be fabricated on a common substrate, it is desirable to make the overall device as short as possible; however, requirements on the allowable channel crosstalk (typically -20 dB for adjacent channels and -30 dB between the dropped and added channels) places a lower limit on grating length. Previous work has demonstrated Gaussian profile gratings [2] which have sidelobes on the short wavelength side of the Bragg wavelength. A double filtering architecture was reported with a transmitted isolation of -40 dB over the drop channel width and a 3dB width of 1 nm [3]. Such an architecture increases the number of gratings needed for each channel and requires that the two grating passbands be identical or passband narrowing occurs.","PeriodicalId":182420,"journal":{"name":"Bragg Gratings, Photosensitivity, and Poling in Glass Fibers and Waveguides: Applications and Fundamentals","volume":"94 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":"115232317","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}

In this work we demonstrate that it is possible to induce a large second-order optical nonlinearity in soda lime and borosilicate glass with the electro-thermal poling procedure described by Myers et al1. We also demonstrate a scheme based on poling to record single-mode waveguides in soda lime.","PeriodicalId":182420,"journal":{"name":"Bragg Gratings, Photosensitivity, and Poling in Glass Fibers and Waveguides: Applications and Fundamentals","volume":"69 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":"114444778","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}
