Electro-optic temporal lenses have recently been recognized as a tool for noise-free, efficient spectral bandwidth manipulation of single-photon wavepackets. However, standard electro-optic time lenses based on single-tone modulation exhibit limited bandwidth manipulation due to material limitations on phase modulation amplitude. Here we numerically investigate the use of complex electro-optic temporal phase modulation patterns for bandwidth compression o","authors_text":"Filip Sosnicki, Michal Karpinski","cross_cats":["quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2018-03-12T17:40:59Z","title":"Large-scale spectral bandwidth compression by complex electro-optic temporal phase modulation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1803.04392","kind":"arxiv","version":2},"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:ed7403f40e214a25bebd651be6b2908f1ea9fd8574a1f0eaa6a9e4340524d151","target":"record","created_at":"2026-05-17T23:56:48Z","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":"3b3eaea2be27188f9d59d51182881221ea693dbc346f2ca6678290b0f3701ae0","cross_cats_sorted":["quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2018-03-12T17:40:59Z","title_canon_sha256":"88869aa937a8cc4e663dbd7a499b55eed603bf7ec555bf50601b86da18366025"},"schema_version":"1.0","source":{"id":"1803.04392","kind":"arxiv","version":2}},"canonical_sha256":"3c1731fc42182bf93377873776a132875fcf2f6302ea4249bd7648fb83526f31","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3c1731fc42182bf93377873776a132875fcf2f6302ea4249bd7648fb83526f31","first_computed_at":"2026-05-17T23:56:48.285048Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:56:48.285048Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ysNtl8KkTUEqnIm1OGTM7+sVqCsONlQ8qfJ22+BifpJ7o66/z9W5wsLAC0mkg8eQfoTtWIZvHhZwsfr7G7zVDg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:56:48.285422Z","signed_message":"canonical_sha256_bytes"},"source_id":"1803.04392","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ed7403f40e214a25bebd651be6b2908f1ea9fd8574a1f0eaa6a9e4340524d151","sha256:649a27a8115c827aa244421ef1c9912baa316c144ccb797e3f4af66c8086f8d1"],"state_sha256":"5f62e298d9d864e56ebecd1265af23d57d2be7f5afc19116b8a0870ad6c564e4"}
