Measurements show that, in contrast to conventional lasers, the threshold gain attains a minimum value for a specific cavity length. The experimental results are explained by an analytical theory for the laser threshold that takes into account the effects of slow-light and random disorder due to unavoidable fabrication imperfections. Longer lasers are found to operate deeper into the slow-light region, leading to a trade-off between slow-light in","authors_text":"Elizaveta Semenova, Jesper Mork, Kresten Yvind, Luisa Ottaviano, Weiqi Xue, Yaohui Chen, Yi Yu","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2015-08-21T18:24:14Z","title":"Threshold Characteristics of Slow-Light Photonic Crystal Lasers"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1508.05349","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":"sha256:339d49bba01fbaf5587c2fa505b7a28fac59bb4eac8925371a44bbd4d7182265","target":"record","created_at":"2026-05-18T01:20:34Z","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":"9cb4482a2406c73ea35b3f07137ceb738c447a709082a9431c60661cb7b74e70","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2015-08-21T18:24:14Z","title_canon_sha256":"2411ea6cdfafa8aca3db6e272741e9ec07556fb4ef330bc282204566060f7332"},"schema_version":"1.0","source":{"id":"1508.05349","kind":"arxiv","version":1}},"canonical_sha256":"69bedcc44295a27abacdaf5c05f10eac4f1e763211331dc7e6e44a50b65f9519","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"69bedcc44295a27abacdaf5c05f10eac4f1e763211331dc7e6e44a50b65f9519","first_computed_at":"2026-05-18T01:20:34.495810Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:20:34.495810Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"xYKx5radu0eF/hQslnWqSlrmShv+fVegxj/LnL4koh9F6SQTqG4/EfTeoTXNDR0xThYhSbCfNeCoihW/ABjJBg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:20:34.496499Z","signed_message":"canonical_sha256_bytes"},"source_id":"1508.05349","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:339d49bba01fbaf5587c2fa505b7a28fac59bb4eac8925371a44bbd4d7182265","sha256:c85b7f1c102e75926f817a5d77afe0813326e30fffd6cebde9630e70ac7d1cb2"],"state_sha256":"46e9e7720285642a0f880041d48589a08c9fc3b755b045faca38e535e8bfc31f"}
