- IOCore® 28Gbps×4ch mass production for volume discount up to 85℃ operation

Immersion Cooling

Immersion Cooling

- EOM and Evaluation board for each IOCore®

Can be placed near heated-up HotChips (CPU, FPGA, ASICs), and can be applied to Immersion Cooling system without any change.

Today's need for large-scale data processing and high-speed communications continues to fuel an insatiable drive towards ever increasing computing power.

The needs extend across the globe, not only to data centers, but also to radio infrastructure, medical equipment, industrial machinery, automobiles, and aerospace.

The silicon photonics technology provided by AIO Core is paving the way for a new era in the convergence of computing and optical technologies.


Our Technology

Design Concept

Optical transceivers, IOCore®, that can operate for long periods of time over an industrial temperature range with extremely high reliability.

Si photonics

IOCore® comprises Mach-Zehnder Interference (MZI) modulators, Germanium photodetectors, Spot Size Converters (SSC) for Laser Diode (LD) coupling and Vertical Grating Couplers.

Quantum Dot LASER

Quantum Dot Fabry-Perot laser realize reliable operation in an industrial teperature range.


LD is positioned and mounted with high precision using passive alignment structures.

Our Products

 IOCore®, enable NRZ signal transmission from 1 Gbps to 25 Gbps and 32 Gbps per channel operable in an industrial temperature range from -40°C to 100°C.
