Project type: Computation and Experiments

Photonic integrated circuits allow us to confine light on silicon-based chips and process information using photons both at the classical and quantum level. One significant advantage of using light as opposed to electrons is its versatility. For instance, we can control the photon’s polarization, modes, wavelength, intensity, etc., translating into plenty of opportunities when developing architectures for applications such as photonic computing. Some of these versatile properties are now being harnessed to create so-called “synthetic dimensions” as well.

Nonlinear effects from controlled light-matter interaction increase the possibilities even further; they allow applications ranging from mimicking the neuron’s response in unconventional computing architectures to generating light sources with wavelengths or spectra otherwise unavailable. Recent research has thus strongly focused on exploring and finely controlling novel light-matter interactions and exploring nonlinear avenues for photonics in on-chip technology.

TREND participants in this project would engage in studying, designing, simulating, and possibly also measuring on-chip nonlinear devices to answer questions like:

  • How to use nonlinear optics as activation functions in optical computing?
  • What optical materials display strong nonlinearities? What applications do they enable? What are the nanofabrication pathways to integrate such materials into photonic circuits, and how can nanostructures strongly enhance this nonlinear light-matter interaction through confinement in space, time or frequency?
  • How to achieve on-chip integrated laser sources with broadband and “exotic” wavelengths using nonlinear light-matter interactions?
  • How can nonlinearities be incorporated into flexible and reconfigurable networks using the emerging concept of synthetic dimensions using the versatile properties of photons?

The research questions are accessible to students from various disciplines and backgrounds including Physics, Materials Science, and Electrical Engineering, and introduce students to lasers, on-chip technology, numerical simulation, and modelling.
