The NbNSNSPD is evanescently coupled to the Si waveguide and connected to the optical fibre through the low-loss SSC comprising a Si inverse taper and large silica-based core. The fabricated SNSPD chip was assembled on a low-loss fibre-coupled module. The fibrecoupling loss of the module is remarkably small (1.9 dB/facet). The fabricated SNSPD module shows system detection efficiency of 32% with the dark count rate of 95 Hz and\ntiming jitter of 75 ps. The measured system detection efficiency is over ten times larger than that of previous waveguide-integrated SNSPDs on the Si platform. The noise equivalent power (NEP) reaches 3.6 × 10-18 WHz-1/2, and the figure of merit (FOM) reaches 1.9 × 108.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_3_full_name_183":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"306","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000017549920","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000017549920"},{"nameIdentifier":"60393732","nameIdentifierScheme":"KAKEN - 研究者検索","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000060393732 /"}],"names":[{"name":"柴田, 浩行","nameLang":"ja"}]}]},"item_3_publisher_212":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing"}]},"item_3_relation_191":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1088/1361-6668/aaf84f","subitem_relation_type_select":"DOI"}}]},"item_3_select_195":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_3_source_id_187":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0953-2048","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Shibata, Hiroyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hiraki, Tatsurou","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tsuchizawa, Tai","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamada, Koji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tokura, Yasuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuo, Sinji","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-02-01"}],"displaytype":"detail","filename":"Supercond.
