据报道,日本京都大学开发了一种使超声波、光及电子元件集成在同一个基片上的一体化元件。该元件可瞬时检测及控制通过硅基片上的光波导信号,并具有小型、稳字性能好等优点。它可角在高速光开关及光谱分 It has been reported that Kyoto University of Japan has developed an integrated device that integrates ultrasonic, optical and electronic components on the same substrate. The element can instantaneously detect and control the optical waveguide signal through the silicon substrate, and has the advantages of small, stable performance and so on. It can angle the high-speed optical switch and spectral points
