Furthermore,\nthe liquid filled hollow core photonic crystal fiber is then used as a vessel to collect Raman scattering\nfrom the sample to determine the molecular fingerprint of the liquid under study.

Compared with the recent micro-structured optical fibre gas cells, the\nproposed HC-PCF gas cell has relatively simpler construction. The gas cell is composed of HC-PCF of 50 cm\nlength and core diameter is 10\n±\n1 m. The HC-PCF is connected to the single mode fibre (SMF) and multi\nmode fibre (MMF) via FC-APC connector. This creates a longitudinal gap between the two fibres which\nacts as a channel of gas diffusion in HC-PCF. The hollow-core and the capillaries in the cladding of HC-PCF\nact as gas channels. A measurement system for low gas concentrations based on this approach is also\nproposed.", "publicationTitle": "Optik", "publisher": "", "place": "", "date": "", "volume": "", "issue": "124", "section": "", "partNumber": "", "partTitle": "", "pages": "3671-3673", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [], "relations": {}, "dateAdded": "2014-07-10T04:30:30Z", "dateModified": "2014-07-10T04:30:30Z" } }, { "key": "E9MIK2CD", "version": 4, "library": { "type": "group", "id": 272775, "name": "Heng Pin", "links": { "alternate": { "href": "https://www.zotero.org/groups/heng_pin", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/272775/items/E9MIK2CD", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/heng_pin/items/E9MIK2CD", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/272775/items/BRIBSCHB", "type": "application/json" } }, "meta": { "createdByUser": { "id": 1503335, "username": "Heng Pin", "name": "Chen Heng Pin", "links": { "alternate": { "href": "https://www.zotero.org/heng_pin", "type": "text/html" } } }, "numChildren": 0 }, "data": { "key": "E9MIK2CD", "version": 4, "parentItem": "BRIBSCHB", "itemType": "attachment", "linkMode": "imported_file", "title": "Thang Thesis.pdf", "accessDate": "", "url": "", "note": "", "contentType": "application/pdf", "charset": "", "filename": "Thang Thesis.pdf", "md5": "3b1362fff74617082faa9e07d39d6df6", "mtime": 1404915593039, "tags": [], "relations": {}, "dateAdded": "2014-07-09T14:20:02Z", "dateModified": "2014-07-09T14:20:02Z" } }, { "key": "BRIBSCHB", "version": 2, "library": { "type": "group", "id": 272775, "name": "Heng Pin", "links": { "alternate": { "href": "https://www.zotero.org/groups/heng_pin", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/272775/items/BRIBSCHB", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/heng_pin/items/BRIBSCHB", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1503335, "username": "Heng Pin", "name": "Chen Heng Pin", "links": { "alternate": { "href": "https://www.zotero.org/heng_pin", "type": "text/html" } } }, "creatorSummary": "Nguyen Manh Thang", "parsedDate": "2013-09-26", "numChildren": 1 }, "data": { "key": "BRIBSCHB", "version": 2, "itemType": "thesis", "title": "Stimulated Raman Scattering in Gas Filled Hollow-Core Photonic Crystal Fibres", "creators": [ { "creatorType": "author", "firstName": "", "lastName": "Nguyen Manh Thang" } ], "abstractNote": "In this thesis I use unique properties of hollow-core photonic crystal fibre (HC-PCF) to study stimulated Raman scattering (SRS) in gaseous medium. HC-PCF offers excellent abilities such as tight confinement of light and matter along diffractionless interaction length in the micron-size core, low loss and adjustable guidance bandwidth. These allow us to achieve extremely high Raman conversion efficiencies and to optimize optical processes for a desired frequency range as well as exploring SRS regimes inaccessible in conventional ways.\nI first give an overview of the guidance mechanisms and fabrication techniques of HC-PCF. There are two main types of HC-PCFs. Hollow-core bandgap fibre (PBG-PCF) have quite low power loss and narrow guidance bandwidth. Hollow-core photonic crystal fibres with Kagomé lattice (Kagomé-PCF) provide broadband guidance and higher loss. The light-matter nonlinear interaction efficiency in HC-PCF has been shown several orders of magnitude higher than those of previous approaches. Next, the theoretical background of SRS is described in detail through both classical and quantum mechanical pictures. Maxwell-Bloch equations governing the spatio-temporal evolution of light-gas interaction system via SRS are also derived.\nFor application purposes, I performed a two consecutive stage pulse compression in H2 gas-filled PBG-PCF by backward stimulated Raman scattering (BSRS). As a result, a signal pulse 20 times shorter than that of the original pump pulse was efficiently generated. Moreover, a new dynamical process generating a train of Raman pulses with flexibly controllable peak intensities have been observed in transient BSRS. We also have been able to generate a broad, mutually coherent, purely rotational Raman frequency comb by a relatively simply setup consisting of a micro-chip pump laser source and two H2 gas-filled HC-PCFs. Lastly, I consider the effect of the collision between gaseous molecules and the fibre core on the spectral linewidth of forward stimulated Raman scattering (FSRS) in a low gas pressure range.", "thesisType": "", "university": "Friedrich-Alexander- Universität", "place": "Erlangen- Nürnberg", "date": "26.9.2013", "series": "", "seriesNumber": "", "numPages": "111", "DOI": "", "ISBN": "", "citationKey": "", "url": "", "accessDate": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [], "relations": {}, "dateAdded": "2014-07-09T14:19:24Z", "dateModified": "2014-07-09T14:19:24Z" } } ]
