2026-IdrDip-02-diii - Development of advanced grating couplers for coupling large free-space optical beams
Scientific-Disciplinary Group
02/PHYS-03 - Experimental Physics Of Matter And Applications
Description
Development of grating couplers for Free-Space Optics (FSO) applications, targeting efficient coupling of large-diameter,low-divergence optical beams from air into integrated waveguides.The activity includes the design and simulation of apodized and non-uniform structures,with scattering engineering to control the phase front and improve alignment tolerance.Multiple photonic platforms will be investigated (Silicon-on-Insulator, Silicon Nitride, Lithium Niobate),analyzing trade-offs between efficiency,bandwidth,and robustness to angular and spatial variations of the incident beam. The work also involves device fabrication and experimental characterization through optical measurements in a free-space
