1. An antenna array system, comprising:
a substrate;
a plurality of layers formed on the substrate, the plurality of layers including a first cladding layer, a core layer, and a second cladding layer;
a plurality of antennas mounted on the plurality of layers and configured to operate as an antenna array, each antenna having a first radiating arm extending in a first direction;
a plurality of photodiodes mounted on the plurality of layers, each photodiode configured to generate an RF current to drive a corresponding antenna to which the photodiode is connected; and
a plurality of micro-bends formed in the plurality of layers and aligned with a corresponding one of the plurality of photodiodes, each micro-bend configured to receive an optical signal from an associated optical waveguide among a plurality of optical waveguides and redirect the optical signal to the corresponding one of the plurality of photodiodes above the plurality of layers,
wherein each micro-bend comprises a reflector or a refractor.
