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": [{"nameIdentifier": "90154", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hiraki, Tatsurou", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "90155", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tsuchizawa, Tai", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "90156", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamada, Koji", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "90157", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tokura, Yasuhiro", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "90158", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Matsuo, Sinji", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "90159", "nameIdentifierScheme": "WEKO"}]}]}, "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", "download_preview_message": "", "file_order": 0, "filename": "Supercond.
