以日本京都大学工学部崎忠教授为首的研究小组,最近成功地研制了一种集超声、电子、光电元件于同一半导体基片上的新型元件。这种新型元件,主要是利用超声波改变光前进方向的声光效应,依靠一体化声、光检测元件,瞬间而自由地控制、检测设置在光导波电路(制作在硅基片上)中的传输光信号。以前,虽也有通过光电路与超声元件相结合的声光元件,但是,通过与光检测用电子元件的一
A research team led by Professor Kazuhiko Akihiro, Faculty of Engineering, Kyoto University of Japan, recently succeeded in developing a novel element that combines ultrasound, electronics and optoelectronic components on the same semiconductor substrate. This new type of element mainly utilizes the acousto-optic effect of changing the light advancing direction by using an ultrasonic wave. By means of an integrated sound and light detecting element, the transmitted light in the optical waveguide circuit signal. In the past, although the acousto-optic element was combined with the ultrasonic element through the optical circuit, the acousto-
