The brief

Analyst view

• Coherent and Lumentum dominate optical transceiver supply; both ship 1.6T modules as of Q4 2026.
• Datacenter and Communications revenue: $1.62B in Q4 FY2026, up 58.6% YoY.
• Manufactures silicon photonics, VCSEL arrays, and passive optical components in-house.

Technical approach

As reported

Silicon photonics

Integrated optics on silicon

Optical signal processing on silicon: lasers, modulators and detectors for high speed and density.

Vertical integration

In-house lasers and optical components

Manufactures VCSEL arrays, ultra-high-power (UHP) lasers, and passive optical components in-house, enabling tight control over yield, performance and cost.

1.6T transceivers

Next-generation datacenter optics

Coherent's 1.6T-DR8 transceiver uses silicon photonics with Marvell Ara 3nm DSP, delivering 200 Gbps per interface for hyperscale AI datacenter links.
