POET Technologies — product portfolio

Updated: 2026-04-29 Status: ✓ Verified via POET press releases and ECOC 2025 technical materials. Customer-shipping status is point-in-time and changes; refresh against 6-K filings. Cross-references: Platform overview · Optical interconnect roadmap · Foundry relationships

1. Product line summary

POET sells optical engines — chip-scale subassemblies that integrate the photonic and electronic devices needed for one direction of data flow (transmit, receive, or both) in an optical transceiver. Engines are sold to OEM module-makers, who package them into pluggable transceivers (QSFP-DD, OSFP, OSFP-XD) or into CPO substrates.

POET does not sell complete transceiver modules and does not sell switch ASICs or DSPs. It sells the photonic-electronic integration core. ✓ (POET technology page)

The current product portfolio is organized around two named platforms (Infinity, Teralight) and a number of specific engine SKUs derived from them:

2. POET Infinity — chiplet-based 400G building block

Announced: 2023-03-02 (Press release) ✓

Architecture: A 400G/lane-pair transmitter chiplet on the POET Optical Interposer. Multiple Infinity chiplets are daisy-chained in a single engine package to deliver 800G (two chiplets), 1.6T (four), or 3.2T (eight) at the engine level.

Disclosed features:

  • Integrated EML lasers, drivers, and MUX (Tx)
  • High-speed photodiodes, TIA, and DMUX (Rx)
  • Extremely small form factor
  • Elimination of wire bonds (flip-chip throughout)
  • Passive assembly of components (no active optical alignment)
  • Monolithically integrated MUX/DMUX in the Si Interposer waveguide layer
  • Drastic reduction in BOM versus discrete TOSA/ROSA designs

Strategic role: Infinity is the architectural primitive — a single mask design that scales by replication rather than redesign. The same Interposer mask family carries through 400G to 3.2T product generations, amortizing NRE across multiple market windows. ✓

3. POET Teralight — 1.6T cost-and-performance optimized

Branded and discussed at: ECOC 2025 Product Focus session (2025-09-28 / 10-02), Copenhagen ✓ (POET ECOC 2025 schedule)

Positioning: “Cost- and Performance-optimized Optical Engines for 1.6T Networks” — Teralight is the volume-class 1.6T product line, distinct from the technical-hero 1.6T 2xFR4 PIC announcement.

Status: Production orders disclosed; specifically the $5M 800G production order announced 2025-10-22 references the same hybrid-Interposer architecture that scales to 1.6T Teralight. ✓ (Production order release)

⚠ Per-SKU pricing and per-customer Teralight ASP are not separately disclosed.

4. 1.6T 2xFR4 transmitter PIC (current technical hero)

Demonstrated at: ECOC 2025 in Copenhagen via the technical paper “Hybrid Integrated 1.6T 2xFR4 Transmitter PIC using a CMOS-based Optical Interposer” presented by CRO Raju Kankipati ✓

Architecture (per POET blog post 2025-09):

  • 4× 2×200G EML arrays flip-chip bonded on the Optical Interposer (Mitsubishi Electric is the disclosed 200G EML supplier per POET-Mitsubishi 2024 partnership) — POET highlights this as “an industry first,” noting the EML-array configuration delivers a “dramatic capacity increase of Indium Phosphide-based EML lasers at a time when the industry is facing shortages”
  • 8× high-speed driver ICs, symmetrically positioned for optimal signal integrity
  • 2× Arrayed-Waveguide-Grating MUX monolithically defined in the Si waveguide layer
  • Single-platform scalability across 800G, 1.6T, and 3.2T

Award: ECOC 2025 “Most Innovative Chip-scale Packaging / Optical Sub-Assembly Product” ✓ (POET ECOC award announcement)

5. 1.6T receiver engines

Launched: 2025-10-06 jointly with Semtech (Press release) ✓

7. External Light Source (ELS) modules

Announced: 2025-09-29 jointly with Sivers Semiconductors (POET-Sivers collaboration release) ✓

Architecture: Sivers’ high-power distributed feedback (DFB) laser technology integrated onto the POET Optical Interposer to produce a chip-scale ELS module compatible with CW-WDM MSA-defined wavelength grids. ELS modules are the laser-supply component that sits external to a CPO substrate, feeding modulators on the switch-adjacent photonic engine.

Target market: $1B+ annual ELS market opportunity by late decade (per POET-Sivers release). ✓

Timeline:

  • H1 2026 — demonstrations
  • End-2026 — production readiness target

8. 3.2T optical engine (in development)

Announced: 2025-11-11 jointly with Quantum Computing Inc (QCi) (POET-QCi release) ✓

Architecture: QCi’s 400G/lane TFLN modulators flip-chip integrated onto the POET Optical Interposer, alongside lasers, drivers, and TIAs.

Form factors targeted: pluggable transceiver + CPO

Funding: POET funds development of QCi’s 400G/lane TFLN modulator. ✓

Timeline: H2 2026 target completion of the modulator development.

Market opportunity: ~$12B by 2030 in pluggable + CPO 3.2T (per LightCounting “Ethernet Optics: Cloud, Enterprise and Telecom,” September 2025).

9. Engine ASP and unit economics

POET does not publicly disclose per-engine ASP. Order-of-magnitude estimates ⚠:

  • 800G engine — $50–$200 per unit (range inferred from $5M production-order volumes against typical 800G transceiver design-window unit counts of 25k–100k)
  • 1.6T engine — $150–$500 per unit (proportional to lane count and EML capacity premium)
  • 3.2T engine — $500–$1,500 per unit at first production (reflects TFLN modulator and 400G/lane premium)
  • ELS module — separate pricing tier; market-comparable DFB ELS modules in the $20–$100 range per unit

The $5.6M Q3 2025 production-order pair and the $5.0M Q3 2025 separate order are the only public revenue-volume anchors. POET FY2024 revenue was approximately $1.6M ⚠ (per FY2024 20-F materials; precise pull deferred for overview). Full year 2025 revenue estimates from analyst coverage range $4–8M ⚠ (Zacks SCR research, May 2025 + November 2025).
