Abstract

An optical phased array (OPA) is a high-speed beam steering device which has no mechanical moving part. An antenna pitch of the OPA is important factor to determine the steering angle. We focused on high-speed phase modulator using an organic electro-optic (EO) polymer and plasmonic waveguide structure which has nano-scale light confinement effect to suppress crosstalk. We proposed OPA structure combined with organic EO polymer and inorganic materials such as Nb2O5 and metals. Mode converters from EO polymer optical phase modulator to Nb2O5 waveguide and plasmonic waveguide were designed by numerical simulation.
