Nonlinear properties of bulk TeO/sub 2/ based glasses were measured with non-resonant nonlinearities an order of magnitude greater than that of silica. Nonlinear absorption was found to be negligible. Recently, low loss single mode fibres have been drawn from the TeO/sub 2/ glass with losses approaching 1 dBm/sup -1/. A dual-channel picosecond laser system has been developed in order to demonstrate nonlinear optical Kerr switching in the fibres providing pulse widths of 20 ps at repetition rates up to 2 GHz.","PeriodicalId":117784,"journal":{"name":"Proceedings of 2002 IEEE/LEOS Workshop on Fibre and Optical Passive Components (Cat.No.02EX595)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123718010","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}
