| Abstract | This work studies ring resonator based electro-optic polymer modulators for use as all-dielectric RF receivers and sensors. In particular, it analyzes and theoretically optimizes ring resonator design for the best possible performance in a given optical link. A fabrication scheme that solves one of the biggest issues in integrating electro-optic polymers into devices is also proposed and experimentally realized.; The first half of this work presents the mathematical analysis of optimizing ring resonator modulators on the basis of the modulation sensitivity and the linearity. General expressions for the modulation response are derived and from this analysis the bandwidth and bias stability of the optimal sensitivity and linearity points is calculated. It is shown that the optimal ring design is always undercoupled and is very dependent on the optical link parameters. The upper limit on the bandwidth of the resonator for "better-than-Mach-Zehnder" performance is shown to be 0.17/Finesse x FSR and is limited by the linearity response.; The second half of this work presents the lift-off poling fabrication scheme that solves the problem of inefficient integration of electro-optic polymers into devices due to their high electrical conductivity. 90-95\% efficiency poling in a device is experimentally demonstrated using standard cladding materials which is a marked improvement from the 60-65\% efficiency previously observed. Optimal ring resonator designs based on the mathematical results of this work are also presented and shown to have E-field sensitivities of 10^{-5} V/m\sqrt{Hz} with a dielectric resonant antenna and 10^{-3} V/m\sqrt{Hz} without. |
