Exploit SilOriX’s proprietary modulator technology along with
the full portfolio silicon photonic devices.


At the backbone of a connected world. From datacom to quantum computing. 


SilOriX modulators enable data transmission at high bandwidth (of up to 100GHz). Along with low insertion losses and CMOS-compatible drive voltages. Those features render SilOriX modulators to be an ideal candidate for future optical interconnects.

6G Networks

Life around the globe is getting more connected each day. Autonoumous driving, the Internet of Things and sophisticated mobile networks like 5G and 6G are already shaping our daily life and will strongly increase to do so in the future. All those technologies rely on fast, compact and cost-efficient optical switches, as provided by SiloriX.


The low energy consumption of the SilOriX technology enables data egress at cryogenic temperatures for applications in cryogenic and quantum computing.
The optical link offers higher bandwidth compared to an electrical link, simultaneously reducing parasitic heating of the temperature sensitive computing core.


Who we are

SilOriX is a high-tech start-up with the focus to scale-up and commercialize efficient solutions for high speed data transmission.

Where we are from

Our knowledge is based on over 10 years of cutting-edge research in the field of silicon-organic hybrid electro-optic interconnects.
