Silicon nitride photonics

In close collaboration with LioniX International, we study low-loss silicon nitride as the material platform for linear and nonlinear optical signal processing. We design and optimize basic building blocks such as ring resonators and Mach-Zehnder interferometers and arrange them in high density circuits for RF photonic signal processing applications, including optical beamforming, microwave photonic filtering, and integrated quantum photonics.
