Here, we propose a design method and optical systems for achromatic surface microstructure composed with a triple-carved-sub-grating. The triple-carved-sub-grating with specified period is designed based on rigorous coupled wave theory, corresponding to Red, Green and Blue (RGB) wavelengths, respectively, with diffraction efficiencies of 1st(-1st) orders reach 47.5% under TE polarization. The surface microstructure with period of 18.9um is realized by integrating the three sub","authors_text":"Jian Han, Jiasheng Xiao, Juan Liu, Yongtian Wang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2017-09-21T11:10:26Z","title":"Design of achromatic surface microstructure for near-eye display with diffractive waveguide"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1709.07262","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":"sha256:1e0732666e300d24ba34b2febc56589d46b843e1b5a551160581be41c95a0e75","target":"record","created_at":"2026-05-18T00:34:36Z","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":"706986b11fd0928df4c0697e630d10dc8d57dcc9be08b5bc5c37ba34d99ffaf8","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2017-09-21T11:10:26Z","title_canon_sha256":"5f4e6393965c3e28a17bfc976b126f98a80bcb12594f350acd729d5ad670df05"},"schema_version":"1.0","source":{"id":"1709.07262","kind":"arxiv","version":1}},"canonical_sha256":"8e8de12d044cd7d3f3c0661453fe62a71183ddefd82c2e6a16996b8119b22450","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8e8de12d044cd7d3f3c0661453fe62a71183ddefd82c2e6a16996b8119b22450","first_computed_at":"2026-05-18T00:34:36.172106Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:34:36.172106Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"vZHAeqilVdahN9GjudZ/ec9F+Iyc9Y0+ZV2z3bKsh29ovyMop2Pw10ZAZXj65dTxLF/qn08PoNr3jUJ5+4HlDw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:34:36.172559Z","signed_message":"canonical_sha256_bytes"},"source_id":"1709.07262","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1e0732666e300d24ba34b2febc56589d46b843e1b5a551160581be41c95a0e75","sha256:45e263bd10c39c705a39d1d483538c6e6668bb45e9c7cc51fc76a68c22917c6d"],"state_sha256":"8525ee48deb9dcb674cdd55945127a2634af49139ef65deb9672c73566a7aaf1"}
