The optical parametric oscillator consists of a periodically poled KTiOPO_4 crystal, both ends of which are spherically polished and mirror-coated. We achieve both phase matching and cavity resonance by controlling only the temperature of the crystal. We observe up to -8.0 dB of squeezing with the bandwidth of 142 MHz. Our technique makes it possible to drive many monolithic cavities simultaneously by a single laser. Hence our monolithic optical parametric oscillator is quite suitable to continuous-v","authors_text":"Akira Furusawa, Hidehiro Yonezawa, Koyo Nagashima","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2010-07-18T12:08:43Z","title":"Generation of squeezed light with monolithic optical parametric oscillator: Simultaneous achievement of phase matching and cavity resonance by temperature control"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1007.2995","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:4d3c5692ba6d27aa48fb5e9ca038121203279beeecd7fcbc56fb4784049db80f","target":"record","created_at":"2026-05-18T02:06:20Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"41da5ea9f3f3c6c774aeb484cc5eafa2459608324416d77fe80672f02b5e02b9","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2010-07-18T12:08:43Z","title_canon_sha256":"a1e538ac40a739f480fe28167e9bc56d4ecab66e7d7bf48e4fe7feb12188ba03"},"schema_version":"1.0","source":{"id":"1007.2995","kind":"arxiv","version":1}},"canonical_sha256":"d766d48ddf30407d825cca3ac8b472f5f3fd182b02f567d84a6621c584286dcc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d766d48ddf30407d825cca3ac8b472f5f3fd182b02f567d84a6621c584286dcc","first_computed_at":"2026-05-18T02:06:20.908510Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:06:20.908510Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bvj2ZvUaqEQ0rUEzF505QSsrZ5pct6vdHdTQWcfiGU2w14O/hdhrZHb6H2PVAwzpnxmoHfLDrsJBl6UchmjjCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:06:20.909327Z","signed_message":"canonical_sha256_bytes"},"source_id":"1007.2995","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4d3c5692ba6d27aa48fb5e9ca038121203279beeecd7fcbc56fb4784049db80f","sha256:332864c61711a5d06535e11a0ee540e072b3690d70c3648a807809e93dc59188"],"state_sha256":"d15d67032aa8781c21ee759a0e63566b9a95cd3f16edd9cbe47fc7492e614bef"}
