A resonant-type optical modulator array connected with antennas can effectively convert a micro/millimeter-wave to a light wave for the uplink of a radio-on-fiber system. We demonstrated the operation of an array that contained four modulators using power simultaneously received by microstrip antennas connected to each modulator. We confirmed that the optical phase change induced by the received power was proportional to the number of connected antennas.
