In this letter, we show that the key features of photonic band structures can be achieved experimentally by the polarization- and momentum-resolved photoluminescence spectroscopy utilizing the light emission properties of SiNx. The two-dimensional spectra clearly reveal the energy-momentum dispersion of band structures which is in perfect agreement with the simulation results. The isofrequency contours can be measured easily by adding a bandpa","authors_text":"Baoli Liu, Chang-Yin Ji, Changzhi Gu, Gang Wang, Peng Fu, Wenze Lan, Yugui Yao","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"physics.optics","submitted_at":"2023-03-19T08:56:08Z","title":"Visualization of Photonic Band Structures via Far-field Measurements in SiNx Photonic Crystal Slabs"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2303.10605","kind":"arxiv","version":3},"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":"sha256:2852cee3ae347787ae097392383ac886e16e59531fda7952c3b8071225d47d52","target":"record","created_at":"2026-07-05T06:02:33Z","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":"76282aead3be411461123d7f91b8febe74526935b95907377889edb472447138","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"physics.optics","submitted_at":"2023-03-19T08:56:08Z","title_canon_sha256":"ecf8fbb3fa2dbc9dda2d074075d7ea0c7d1740c680682e03c997272dacba6036"},"schema_version":"1.0","source":{"id":"2303.10605","kind":"arxiv","version":3}},"canonical_sha256":"80fd7087013c44f822aa759a2c51f42b6972a9a63489d608a3c055818f614982","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"80fd7087013c44f822aa759a2c51f42b6972a9a63489d608a3c055818f614982","first_computed_at":"2026-07-05T06:02:33.292791Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:02:33.292791Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"TKag9VM/5oPGY24EQ9ozKhx1sN8rPAuJ6Lp4G8iZIZIoMcbDueSig+S4GyTYYtMml95wx7H+cdE1f6lXxLMCDw==","signature_status":"signed_v1","signed_at":"2026-07-05T06:02:33.293257Z","signed_message":"canonical_sha256_bytes"},"source_id":"2303.10605","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2852cee3ae347787ae097392383ac886e16e59531fda7952c3b8071225d47d52","sha256:18da44a62c15cb133c5b6da99b9aebe62480629ef21dfedb97469b300299dc82"],"state_sha256":"1b97e8e03ba8d1805a7e5a3a07e67ee6debe825f52d2cc225f8bd34c10e8f578"}
