摘要
基于双棱镜耦合m线技术提出了一种新型的平面波导强度调制器。由于质子交换平面波导的导波层在加上电场后折射率发生变化,从而引起棱镜耦合输出的m线强度的变化,实现电光调制。讨论了电极间隙宽度和导波层吸收对器件性能的影响。与其他类型强度调制器相比,这种调制器具有简单的电极结构,而且调制带宽可达40 GHz 以上。
Abstract
A new type of electrooptic modulator using annealed proton exchanged (APE) planar lithium niobate waveguide is proposed. Two prism coupling method is used to implement the electrooptic modulation is proposed by changing the angle of the m lines before and after the voltage applied on the electrodes. This type of the modulator is easily fabricated and can be operated at more than 40 GHz bandwidth.
