SPINONICS

Integrated devices based on spin-orbit photonics

This Project is funded by the European Commission through the H2020 Marie Skłodowska-Curie Individual Fellowships. The Project aims to study novel devices based on spin-orbit photonics.

Spin dependent deflection of circularly polarized beam by a Pancharatnam-Berry Phase metasurface.

Several breakthrough have been achieved in wavefront shaping owing to the technological advances in metasurface fabrication leading to the development of planar optics wherein the phase and polarization of the beam can be modified due to the Geometric Phase associated with the inhomogeneous distribution of the individual nanostructures. This Project aims to study novel integrated photonic devices based on spin-orbit interactions in anisotropic materials with an inhomogeneous distribution of optic axis resulting in Pancharatnam-Berry Phase (PBP).
In this Project novel integrated photonic components and devices with new functionalities based on PBP will be developed, e.g, directional couplers, polarization-dependent routers, PBP based resonators and so on. In the nonlinear regime light itself writes an inhomogeneous distribution of the optic axis resulting in dynamic integrated devices.

This project has received funding from the European Union's Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 889525.
