Here we study the effect of suppressing DCR using the various optical bandpass filters cooled at 3 K. The DCR, which is dominated by the background blackbody radiation at room temperature through an optical fiber, can be strongly suppressed by introducing the cold filter. Using the bulk commercial filter with the bandwidth of 10 nm and the high transmission above 85 %, the DCR is improved about 29 dB with 2.4 dB decreasing of the system detection efficiency (\u03b7). The noise equivalent power (NEP) reaches 1.5 \u00d7 10-18 and the figure of merit (FOM) reaches 1.8 \u00d7 109. These values are compared to the results using other type of filters.", "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": "IEEE"}]}, "item_3_relation_191": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_name": [{"subitem_relation_name_text": "https://doi.org/10.1109/TASC.2016.2631947"}], "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1109/TASC.2016.2631947", "subitem_relation_type_select": "DOI"}}]}, "item_3_rights_192": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 2016 IEEE.
