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 \u00d7 10-18 WHz-1/2, and the figure of merit (FOM) reaches 1.9 \u00d7 108.", "subitem_description_type": "Abstract"}]}, "item_3_full_name_183": {"attribute_name": "\u8457\u8005\u5225\u540d", "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 - \u7814\u7a76\u8005\u691c\u7d22", "nameIdentifierURI": "https://nrid.nii.ac.jp/ja/nrid/1000060393732 /"}], "names": [{"name": "\u67f4\u7530, \u6d69\u884c"}]}]}, "item_3_publisher_212": {"attribute_name": "\u51fa\u7248\u8005", "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": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "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": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Shibata, Hiroyuki"}], "nameIdentifiers": [{"nameIdentifier": "90154", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hiraki, Tatsurou"}], "nameIdentifiers": [{"nameIdentifier": "90155", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tsuchizawa, Tai"}], "nameIdentifiers": [{"nameIdentifier": "90156", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamada, Koji"}], "nameIdentifiers": [{"nameIdentifier": "90157", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tokura, Yasuhiro"}], "nameIdentifiers": [{"nameIdentifier": "90158", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Matsuo, Sinji"}], "nameIdentifiers": [{"nameIdentifier": "90159", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "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.
