提出了一种新型的、紧凑的、可调谐的、由两个Y结反射器组成的平面波导环结构，用于光学和射频信号处理。由于钛扩散LN波导的低传播损耗，初步器件显示出6.5/spl times/10/sup 4/的高品质因数。估计了电场对环路的可调谐性。
A novel, compact, and tunable lithium niobate (LN) planar waveguide loop structure composed of two Y junction reflectors is proposed for optical and radio frequency signal processing applications. The preliminary device shows a high quality factor of 6.5/spl times/10/sup 4/, due to the low propagation loss of the titanium-diffused LN waveguide. The tunability of the loop by electric field is estimated.
