In our experiment, bulk glasses of chalcogenide systems Ga-Ge-S, As/sub 2/S/sub 3/ and Ga-Ge-S thin films have been used. Photo-structuring of the bulk glasses has been obtained by using low energy (< 2.5 nj) fs laser pulses with wavelength of 815 nm, while the films have been photo-structured by using both fs and nitrogen lasers. Spherical structures in the bulk glasses have been found whose geometrical form and size depend on both the sample translation velocity and the laser pulse energy. With increasing the sample translation velocity up to 3 cm/s, and for values of the average laser power of 150 mW, the spherical structures disappear and flat waveguides are created. The manufacturing laser threshold for bulk chalcogenide glasses was found to be about 2 /spl middot/ 10/sup 10/ W/cm/sup 2/. For the case of films irradiated by the nitrogen laser a blue shift of the optical absorption edge and a decrease of the refractive index were measured. The considerable and controllable change of the optical parameters allowed us to create waveguides showing the possibility of realizing integrated optical circuits with high density of elements.","PeriodicalId":445290,"journal":{"name":"Proceedings of 2005 IEEE/LEOS Workshop on Fibres and Optical Passive Components, 2005.","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129510209","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}

Besides the most studied technique of bulk poling, recently a novel technique where domain inversion occurs just in a surface layer using photoresist or silica masks has been devised and studied. This surface periodic poling (SPP) approach is best suited when light is confined in a thin surface guiding layer or stripe, as in the case of optical waveguide devices. Also, we found that SPP respect to bulk poling offers two orders of magnitude reduction on the scale of periodicity, so that even nanostructures can be obtained provided a high resolution holographic mask writing technique is adopted. We were able to demonstrate 200 nm domain size, and also good compatibility with alpha-phase proton exchange channel waveguide fabrication. Our first experiments on lithium tantalate have also shown that the SPP technology appears to be applicable to this crystal (SPPLT), whose properties can allow to overcome limitations such as optical damage or UV absorption still present in PPLN devices. Finally, the issue of SPP compatibility with proton exchange waveguide fabrication will be addressed.","PeriodicalId":445290,"journal":{"name":"Proceedings of 2005 IEEE/LEOS Workshop on Fibres and Optical Passive Components, 2005.","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114447794","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}
