POET Technologies and Semtech have introduced 1.6T receiver optical engines aimed at AI and cloud data center networks. The new products integrate Semtech’s 200G-per-lane FiberEdge technology into POET’s Optical Interposer platform, producing compact chip-scale devices designed to boost sensitivity and reduce power consumption at 200G/lane. Evaluation units are now available for qualified customers.
The companies are offering two variants: a DR8 engine optimized for short-reach AI cluster links and a dual-FR4 engine for longer intra-datacenter connections. Both versions simplify transceiver manufacturing by integrating optical and electronic components at the chip level, reducing bill of materials and assembly steps. POET noted that the approach enhances signal integrity while lowering energy use, key factors for large-scale AI infrastructure.
By combining POET’s wafer-level photonic integration with Semtech’s tested receive path technology, the collaboration delivers transceiver engines targeting 1.6T modules. POET executives highlighted the importance of these products for expanding the company’s footprint in the high-speed optical ecosystem, while Semtech emphasized the power and signal-integrity benefits of the joint design.
• 1.6T DR8 and 2×FR4 optical engines now sampling to customers
• Integrates Semtech FiberEdge TIAs on POET’s Optical Interposer platform
• Supports 200G/lane receive paths with lower power and higher sensitivity
• Designed for AI cluster and intra-datacenter connectivity
• Available for customer evaluation through POET
“We expect customers will quickly understand the market impact these products can make on their transceiver offerings and the resulting benefit to their customers,” said Raju Kankipati, Chief Revenue Officer, POET Technologies.
🌐 Analysis: The POET–Semtech collaboration underscores the push toward 200G/lane optical connectivity as AI data centers demand higher bandwidth and energy efficiency. Rival platforms from Broadcom, InnoLight, and Coherent are also moving into 1.6T and beyond, highlighting a competitive landscape where integration strategies like POET’s Optical Interposer could differentiate on manufacturability and power savings.
