Flat optics

Flat optics

Want to integrate nanoscale optical components in your innovative products such as cameras, displays or sensor systems? Imec helps you with the full development process.

For centuries, optical instruments remained bulky and expensive. They were produced by refining mechanical parts, usually in glass, that manipulate the light in order to sense, measure, make projections, ...

It’s only recently that there’s an alternative for this traditional approach: flat optics delves into the toolbox of the semiconductor industry. The idea is to create nanostructures that fulfill optical functions. Examples of such functions are focusing and color splitting – at a wavelength scale and with visible as well as infra-red light.

Want to dive into this toolbox? Imec is ready to help you with the development and integration of such flat optics components in its state-of-the art cleanrooms. And we can guide you towards large-scale manufacturing.

Advantages of flat optics

The main advantage of flat optics? Its compactness compared to traditional macro-optics. Moreover, flat optics components are processed using well-established techniques from the microchip industry, such as lithography and thin-film deposition. The result is that manufacturing becomes cheaper and easier to upscale.

Some other advantages of flat optics are:

  • They exhibit high design flexibility and material flexibility.
  • They can be perfectly alignmed and optimized at pixel level.
  • They're compatible with further post processing on complex integrated circuits.
