Single sideband radio over fiber transmission with an integrated polymeric waveguide ring resonator

Besides the general advantages of microwave photonic filters for signal processing, the integrated waveguide ones have their potential to bring down volume and weight of systems. An integrated polymeric waveguide ring resonator was designed and fabricated by a simple UV-based soft-lithography technology, with which the single sideband filtering response was realized and 20 Mbps QPSK signal carried by 14.35 GHz microwave was transmitted successfully over 25 km single mode fiber.
