Optoelectronic applications of surface acoustic waves in visible and infrared wavelengths

With the development of surface acoustic wave (SAW) technology, SAW devices have been widely applied in various areas, especially in optoelectronics fields. Compared with traditional optoelectronic devices, SAW devices exhibit higher sensitivity and can realize passive wireless operating. Although previously reported optoelectronic applications of the SAW mainly focused on ultraviolet wavelengths, recent years have witnessed its potential in visible and infrared wavelengths. In this review, the optoelectronic devices and applications of the SAW in visible and infrared wavelengths, especially on photodetection and photoelectric modulation, are introduced in detail. The research status of these devices are analyzed emphatically, including their structures, working principles, key parameters, acoustic wave types, material compositions, and performances. Finally, the future challenges and upcoming perspectives of SAW optoelectronic applications in the visible and infrared wavelengths are discussed.
