Foundry | Material Platforms
A material platform built on silicon waveguides, on which active components such as modulators and photodetectors can be integrated on the same chip. It is widely used for photonic integrated circuits in optical communications and sensing.
Silicon waveguides (SOI)
Photonic integrated circuits with active components
This varies by foundry and by run. Please contact us.
Transmit and receive circuits with modulators and photodetectors
Large photonic integrated circuits making heavy use of waveguides, splitters and couplers
Designs premised on combination with electronics
If low-loss passive circuits or the visible range are the main requirement, silicon nitride may suit better. If a light source has to be integrated on the chip, consider InP.
Scope
Assess the fit of the platform from the component types and the target wavelength.
Waveguides, splitters, couplers, filters and the other elements a circuit is built from.
Modulators, photodetectors and the other elements linking electrical and optical signals.
Used mainly for designs in the near-infrared optical communication bands.
Which components are actually available and what can be designed are set by the target foundry’s PDK and design rules.
Design workflow
How the design process works, including analysis and simulation, is covered under Solutions.

It is fine to come to us mid-design. We will advise on the fit of the platform and how to proceed.
