In this work, we present a proof-of-concept demonstration of a high-capacity optical transmitter (Tx) that integrates four SiPh-based Mach\u2013Zehnder modulators (MZMs), an O-band ultra-wideband quantum-dot comb laser diode (QDLD), and a multi-core fiber (MCF), enabling simultaneous multiplexing in both wavelength and spatial domains. The QDLD comb laser source generates a large number of evenly spaced, phase-coherent wavelength channels from a single device, eliminating the need for multiple discrete lasers and simplifying system complexity. In the proof-of-concept experiments, repeated measurements are performed for each comb line to ensure statistical reliability. Each comb line is modulated using four-level pulse amplitude modulation (PAM4) at a data rate of 212 Gbit\/s. By utilizing 23 comb lines with sufficient signal-to-noise ratio (SNR), in combination with seven spatial cores in an MCF, the system could achieve an aggregate data rate of up to 34.132 Tbit\/s (212 Gbit\/s\u2009\u00d7\u200923 comb lines \u00d7 7 cores). The average transmitter-dispersion-eye-closure-quaternary (TDECQ) is within 2.02\u2005dB after 2\u2005km of fiber transmission.<\/jats:p>","DOI":"10.1364\/oe.604457","type":"journal-article","created":{"date-parts":[[2026,6,10]],"date-time":"2026-06-10T14:00:10Z","timestamp":1781100010000},"page":"24318","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Silicon-photonics transmitter using ultra-wideband quantum-dot comb laser-diode towards 34.132 Tbit\/s\/fiber"],"prefix":"10.1364","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5612-5732","authenticated-orcid":true,"given":"Yun-Han","family":"Chang","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00se2k293","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Hon Hai Research Institute"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1290-5419","authenticated-orcid":true,"given":"Yuan-Zeng","family":"Lin","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00se2k293","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Han","family":"Lin","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00se2k293","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Heng","family":"Hong","sequence":"additional","affiliation":[{"name":"Hon Hai Research Institute"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao-Chung","family":"Kuo","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00se2k293","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Hon Hai Research Institute"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chi-Sen","family":"Lee","sequence":"additional","affiliation":[{"name":"Industrial Technology Research Institute"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sin-Jhu","family":"Wun","sequence":"additional","affiliation":[{"name":"Industrial Technology Research Institute"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8842-2512","authenticated-orcid":true,"given":"You-Chia","family":"Chang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00se2k293","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7488-2611","authenticated-orcid":true,"given":"Chi-Wai","family":"Chow","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00se2k293","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,6,23]]},"reference":[{"key":"oe-34-13-24318-R1","doi-asserted-by":"publisher","first-page":"751","DOI":"10.1038\/s41467-024-44750-0","type":"journal-article","volume":"15","author":"Shekhar","year":"2024","journal-title":"Nat.
