GF Fotonix — papers, conferences, and technical disclosures
Updated: 2026-04-29 Status: ✓ Catalogued via Optica DOIs, IEEE Xplore, GF Newsroom, and conference programs. Coverage 2020-2026; not exhaustive but represents the load-bearing technical disclosures. Cross-references: Fotonix process overview · Process roadmap · Patents overview
1. Bibliography framing
GF’s technical disclosure cadence runs through three primary venues:
- OFC (Optical Fiber Communication Conference) — March; the highest-impact datacom-photonics venue
- ECOC (European Conference on Optical Communication) — September; OFC counterpart
- CLEO (Conference on Lasers and Electro-Optics) + IEEE Photonics + IEEE Summer Topicals + Photonics West — secondary venues with strong device-physics representation
Plus customer co-disclosures at investor events (Marvell, Broadcom analyst days), GF’s own technology blog, and ad-hoc IEEE Xplore publications.
This bibliography is organized by year, with DOIs / Optica IDs / IEEE document numbers where available. Papers without a stable DOI are referenced via conference program slot or GF Newsroom URL.
2. 2020 — Foundational 45CLO disclosure
| Year | Title / venue | Authors / context | DOI / link |
|---|---|---|---|
| 2020 | 45 nm CMOS — Silicon Photonics Monolithic Technology (45CLO) for next-generation, low-power, and high-speed optical interconnects — OFC 2020 invited paper | GlobalFoundries technical staff (multiple) | Optica T3H.3 ✓ ; IEEE document 9083571 ✓ |
This is the founding technical disclosure of what became Fotonix. The 45CLO designation predates the “Fotonix” branding (which was introduced March 2022). The paper introduced the 45 nm SOI monolithic CMOS-Silicon Photonics integration scheme, validated the photonic-device library (modulators, photodetectors, waveguides), and made the case for productization.
3. 2022 — Fotonix launch
| Date | Disclosure | Source |
|---|---|---|
| 2022-03-08 | GF Fotonix platform launch — first commercial 300mm monolithic SiPh + 300 GHz RF-CMOS productized foundry; ecosystem of partners revealed | GF press release via PRNewswire ✓ |
The launch positioning emphasized the customer ecosystem (Broadcom, Cisco, Marvell, NVIDIA, Macom, Ayar Labs, Lightmatter, Ranovus, PsiQuantum, Xanadu, Ansys, Cadence, Synopsys) more than novel device disclosure. The technical content drafts on the OFC 2020 / 2021 / 2022 invited-paper series.
4. 2024 — Next-generation Fotonix
| Year | Title / venue | DOI / link |
|---|---|---|
| 2024 OFC | Latest Progress and Challenges in 300 mm Monolithic Silicon Photonics Manufacturing (Th3H.2) | Optica ✓ |
| 2024 CLEO | 300-mm monolithic CMOS silicon photonics foundry technology (Invited) (ATu3H.1) | Optica ✓ |
| 2024 GF blog | Next-gen GF Fotonix: Redefining Flexibility, Bandwidth Upgrades & Full Turnkey Support | GF Newsroom ✓ |
| 2024 GF blog | More Compute Power, Better Connectivity: Combining Proven CMOS Chip Fabrication with Silicon Photonics to Move Data at the Speed of Light | GF Newsroom ✓ |
| 2024 GF blog | Silicon Photonics: A Marriage of Optical and Digital on GF’s RF Process | GF Newsroom ✓ |
| 2024 GF blog | How Silicon Photonics is Speeding Up Generative AI | GF Newsroom ✓ |
The 2024 OFC paper is the canonical Fotonix manufacturing-state-of-the-art reference; it covers the modulator library expansion (MZM + MRM + RAMZM), packaging upgrades, PDK compact-model improvements, and yield characterization. The CLEO 2024 invited overview is the higher-level companion that anchors the 300mm CMOS+photonics framing.
5. 2025 — Customer ecosystem and Enosemi IP
| Date | Disclosure | Source |
|---|---|---|
| 2025-03-31 | Ayar Labs unveils first UCIe optical chiplet for AI scale-up — TeraPHY at 4-8 Tbps with SuperNova 16-wavelength source | Ayar Labs ✓ ; BusinessWire ✓ |
| 2025-08-25 | Xscape Photonics + Tower Semiconductor on-chip multi-wavelength laser — competitive milestone (Tower, not GF, but reshapes the SiPh foundry market) | Tower ✓ |
| 2025 (mid) | Ansys Lumerical certified for GF Fotonix — EDA tool certification milestone | Ansys investor release ✓ |
| 2025 (mid) | Enosemi silicon-validated electronic-photonic design IP available in Fotonix platform — IP-block ecosystem expansion | Photonics Online ✓ |
| 2025-06-04 | NLM Photonics announces Selerion-BHX — crosslinkable thermoset OEO material with r33 = 1000 pm/V; foundry-integration target | NLM Photonics ✓ ; Optica corporate news ✓ |
| 2025-11-12 | Tower CPO Foundry technology — competitive response to GF’s CPO leadership | Tower ✓ |
| 2025-11-17 | GF acquires AMF — strategic milestone | GF press release ✓ |
The 2025 calendar is heavy on ecosystem announcements (EDA certification, IP block availability, customer milestones) rather than novel device-physics papers. This is consistent with the platform’s productization phase.
6. 2026 — EO-polymer commercial PDK, NLM SOH samples
| Date | Disclosure | Source |
|---|---|---|
| 2026-03-16 | LWLG GDSFactory PDK live for GF Fotonix — first commercial productized EO-polymer modulator design flow on a 300mm SiPh foundry; slot-waveguide process optimization confirmed | Stocktitan ✓ |
| 2026-03-16 | NLM Photonics samples Silicon-Organic Hybrid PICs at GF (AMF GP) — second-gen on AMF HP; HP PDK 6.0 in development | NLM Photonics ✓ ; Optica corporate news ✓ |
| 2026-03-17 to 19 | OFC 2026 Los Angeles — multiple Fotonix-related sessions (specific paper IDs ⚠ to be catalogued from the OFC 2026 program) | OFC 2026 program ⚠ |
| 2026-04-22 | Marvell acquires Polariton Technologies — POH-modulator IP integration target on Fotonix | Marvell newsroom ⚠ confirm exact PR URL |
