We propose a new electro-optic microwave-lightwave converter using two orthogonal optical waveguides and patch antennas embedded with two orthogonal gaps. Wireless microwave signals can be received, separated and converted directly to lightwave signals through optical modulation using the proposed device. This device operates with no external power supply and with low microwave distortion. In addition, it enables us to measure the magnitude, phase and polarization of the wireless signal simultaneously. Experimental demonstrations of the device were presented at the operation frequency of 26 GHz. The device can be applied for electromagnetic compatibility test in the radio-over-fiber link.

ABSTRACTLead-zirconate-titanate, Pb(Zr0.53Ti0.47)O3, films were produced by the sol-gel method from alkoxide and acetate precursors in a 2-methoxyethanol solvent system. The PZT films were deposited on platinized silicon and single-crystal SrTiO3 substrates for electrical and optical characterization, respectively. The processing parameters, especially excess PbO content and annealing conditions, were shown to have a significant effects on the properties of PZT films. Epitaxial PZT films deposited on SrTiO3 waveguided over 10 mm distances with propagation losses as low as 5.9 dB/cm at 783 nm and a linear electro-optic effect was also demonstrated.
