As compared with the conventional PCFs, the proposed PCF has a following feature in its structure; the first ring area contains no air holes, and the third ring area also contains no air holes. Then the proposed PCF has a large core and a concentric missing ring. The chromatic dispersion was numerically simulated by the semi-vector finite difference method. The chromatic dispersion becomes almost flat in 1300 /spl sim/ 1650 nm wavelength range when the air hole diameter is about 0.35 times the air hole spacing. Especially the chromatic dispersion is -1 /spl sim/ 0 (ps/nm/km) in the above wavelength range when the air hole spacing is 1.25 /spl mu/m and the air hole diameter is 0.43 /spl mu/m.","PeriodicalId":445290,"journal":{"name":"Proceedings of 2005 IEEE/LEOS Workshop on Fibres and Optical Passive Components, 2005.","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126804370","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}

Depending on the optical system specifications, either edge filters or band-pass filters are required. In this last category, special attention is paid to narrow band transmission filters which use is greatly expanding in both telecommunication and spectrometry. In this work, narrow band transmission filters are proposed which performance is varied along the filter surface. These variable filters allow the construction of compact spectrometers that are useful in all applications where both weight and dimensions are required to be very low. Transmission filters operating in a wide wavelength range, visible and shortwave near infrared, are described. Their peak transmittance is linearly moved in one direction along the component surface, within a total length smaller than 10 mm. The filter structure is composed of a thin-film multilayer stack containing both metal and dielectric materials.","PeriodicalId":445290,"journal":{"name":"Proceedings of 2005 IEEE/LEOS Workshop on Fibres and Optical Passive Components, 2005.","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131352600","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}
