Taking nonlinear optics to integrated platforms

Since the 60’s the peculiar nonlinear effects of certain materials have allowed for conversion and mixing of laser wavelengths, but typically in big laboratory systems.

We are bringing this technology to wafer-scale production of photonic integrated circuits, enabling complex phenomena on a scalable platform. Using our platform, existing excellent laser diodes commercially available at visible wavelengths can be converted to UV wavelengths with great flexibility.
