We report in-plane slotted patch antenna-coupled electro-optic phase modulators with a carrier-to-sideband ratio (CSR) of 22 dB under an RF power density of 120 W/m(2) and a figure of merit of 2.0 W(-1/2) at the millimeter wave frequencies of 36-37 GHz based on guest-host type of second-order nonlinear polymer SEO125. CSR was improved more than 20 dB by using a SiO(2) protection layer. We demonstrate detection of 3 GHz modulation of the RF carrier. We also derive closed-form expressions for the modulated phase of optical wave and carrier-to-sideband ratio. Design, simulation, fabrication, and experimental results are discussed.
我们报道了基于客体-主体型二阶非线性聚合物SEO125的面内开槽贴片天线耦合电光相位调制器，在120 W/m²的射频功率密度下，载波与边带比（CSR）为22 dB，在36 - 37 GHz毫米波频率下品质因数为2.0 W⁻¹/²。通过使用SiO₂保护层，CSR提高了20 dB以上。我们展示了对射频载波3 GHz调制的检测。我们还推导了光波调制相位和载波与边带比的闭式表达式。讨论了设计、仿真、制造和实验结果。
