Control light where systems reach their hardest limits.
Bandwidth, latency, precision, power, reach, and integration are driving photonics closer to compute, deeper into aerospace systems, and into the core of quantum information technology.
01 / AI interconnect
Photonics moves closer to compute.
As AI systems scale, electrical reach, power, and bandwidth become critical constraints. Integrated photonics enables high-bandwidth, energy-efficient connectivity from racks and clusters toward XPUs, packages, and chips.
Scale-out
Across racks and clusters
High-capacity optical connectivity supports conventional network-scale AI infrastructure and long-reach data movement.
Scale-up
Between XPUs
High-bandwidth, low-latency fabrics use TFLN, ELN™, SiPh, and SiN for modulation, routing, and integrated optical connectivity.
Scale-in
At chip and package level
Dense integration and optical I/O move connectivity inside the compute domain through integrated Tx/Rx and co-packaged optics.
TFLN
High-speed electro-optic devices
Strong, low-loss modulation for links approaching compute, including Mach–Zehnder, phase, and IQ modulation with development toward multichannel optical I/O.
SiPh
Integrated photonic devices
Modulators, Ge photodetectors, WDM functions, routing, and coupling combine toward compact Tx/Rx and optical-engine architectures.
SiN
Low-loss passive photonics
WDM, filtering, routing, and external-laser distribution manage optical signals across integrated systems and photonic interposers.
System objective: higher bandwidth through high-speed electro-optic modulation, denser integration through integrated devices, and lower loss through passive optical routing—including 800G/1.6T CPO modules, 64T optical-engine development, and high-density optical I/O.
