However, light extraction efficiency of diamond is low because of its high refractive index of diamond. To meet the requirement, we performed the numerical optimization using a FDTD method of the grating coupler over the diamond substrate.\n\nMethod\nWe performed the numerical optimization of the number and pitch of grating using a Finite Difference Time Domain (FDTD) method of the grating coupler over the diamond substrate. We compared the enhancement of the optical intensity with and without grating (FIG. 1). The increased rate represents the enhancement of electric field with grating with respect that without grating.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"The 2nd International Forum on Quantum Metrology and Sensing への出席","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sato, Takumi"}],"nameIdentifiers":[{"nameIdentifier":"856298","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitaizumi, Takahiro"}],"nameIdentifiers":[{"nameIdentifier":"856299","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Saichi, Kota"}],"nameIdentifiers":[{"nameIdentifier":"856300","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Igarashi, Ryuji"}],"nameIdentifiers":[{"nameIdentifier":"856301","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohshima, Takeshi"}],"nameIdentifiers":[{"nameIdentifier":"856302","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masuyama, Yuta"}],"nameIdentifiers":[{"nameIdentifier":"856303","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iwasaki, Takayuki"}],"nameIdentifiers":[{"nameIdentifier":"856304","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hatano, Mutsuko"}],"nameIdentifiers":[{"nameIdentifier":"856305","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Jelezko, Fedor"}],"nameIdentifiers":[{"nameIdentifier":"856306","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kusakabe, Moriaki"}],"nameIdentifiers":[{"nameIdentifier":"856307","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masaki Sekino"}],"nameIdentifiers":[{"nameIdentifier":"856308","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yatsui, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"856309","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Igarashi, Ryuji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"856310","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohshima, Takeshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"856311","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masuyama, Yuta","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"856312","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hatano, Mutsuko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"856313","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Improving Magnetic Sensitivity in Magnetometer with Nitrogen-Vacancy Center in a Bulk Diamond using Grating Coupler","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Improving Magnetic Sensitivity in Magnetometer with Nitrogen-Vacancy Center in a Bulk Diamond using Grating Coupler"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-03-18"},"publish_date":"2020-03-18","publish_status":"0","recid":"79554","relation_version_is_last":true,"title":["Improving Magnetic Sensitivity in Magnetometer with Nitrogen-Vacancy Center in a Bulk Diamond using Grating Coupler"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T22:18:07.682127+00:00"}
