Photonics: Powering the Optical Foundation of Data Center, AI and Coherent Networks
In today's high-performance computing landscape, the shift toward optical interconnects for terabit-scale AI data center connectivity places new demands on the optical building blocks at the very core of the network: the lasers, amplifiers, and photodetectors that generate, boost, and receive light. Semtech’s photonics platform supports the explosive demand for data center scale-up, scale-out and scale-across optical interconnects including NPO, CPO and related solutions. Semtech's photonics technology — built on US-based vertically integrated Indium Phosphide (InP) chip design and manufacturing — delivers the gain chips, DFB laser chips, and PIN/APD photodetectors that enable high performance optical interconnects up to 3.2T and beyond.
The Semtech Advantage: US-based Vertically Integrated Optical Chip Manufacturing
Semtech's Photonics portfolio is engineered from end-to-end to support our customers. From device design to epitaxial wafer growth to final product, Semtech ensures tight control over performance, reliability, and supply continuity that other suppliers cannot match. Our state-of-the-art clean rooms in Southern California provide wafer growth and processing from engineering development through volume manufacturing. Our optical building blocks are designed to maximize optical performance while minimizing size, power, and cost for high-volume deployment:
- GainCore™: Gain Chips & SOAs — enabling tunable lasers (ITLAs) for coherent and high-power CW optical transmitters for data center, AI and telecommunications applications
- LambdaCore™: DFB Laser Chips — delivering high output power with narrow linewidth and low relative intensity noise (RIN) for NPO, CPO, coherent-lite and related interconnects
- PhotoCore™: Photodiodes (PIN/APD) — high-responsivity PIN, monitor, and avalanche photodiodes optimized to work with Semtech TIAs for high-performance receivers in data center AI and access applications.
Addressing Critical Industry Challenges
As artificial intelligence workloads drive unprecedented bandwidth demand, and networks transition to coherent 800G/1.6T optical transport, the optical front end has become a critical bottleneck. Laser sources must deliver higher power and narrower linewidth without sacrificing reliability; amplifiers must extend reach and boost signal budgets; and photodetectors must keep pace with ever-higher data rates — all while meeting the size, power, and cost constraints of modern optical modules. Semtech's Photonics technology directly addresses these constraints, providing the foundational optical components that enable coherent transceivers, ITLA-based tunable lasers, silicon photonics engines, and PON/FTTx access equipment to scale reliably.
Future-Proof Your Optical Network Infrastructure
With Semtech's vertically integrated Photonics portfolio, module and system manufacturers gain a single source for the gain chips, DFB lasers, and photodetectors that anchor next-generation optical networks — backed by in-house InP fabrication, rigorous reliability testing, and custom chip design services. This breakthrough integration ensures that optical component supply and performance don't become the limiting factor in scaling AI, coherent, and access network infrastructure.
