Graphene-based fine-tunable optical delay line for optical beamforming in phased-array antennas

The design of an integrated graphene-based fine-tunable optical delay line on silicon nitride for optical beamforming in phased-array antennas is reported. A high value of the optical delay time (τ =920  ps) together with a compact footprint (4.15  mm ) and optical loss
