摘要
En 中文
Acousto-optic modulation in piezoelectric materials offers the efficient method to bridge electrical and optical signals. It is widely used to control optical frequencies and intensities in modern optical systems including Q -switch lasers, ion traps, and optical tweezers. It is also critical for emerging applications such as quantum photonics and non -reciprocal optics. Acousto-optic devices have recently been demonstrated with promising performance on integrated platforms. However, the conversion efficiency of optical signals remains low in these integrated devices. This is attributed to the significant challenge in realizing large mode overlap, long interaction length, and high power robustness at the same time. Here, we develop acousto-optic devices with gallium nitride on a sapphire substrate. The unique capability to confine both optical and acoustic fields in sub -wavelength scales without suspended structures allows efficient acoustooptic interactions over long distances under high driving power. This leads to the complete optical conversion with integrated acousto-optic modulators. With the unidirectional phase matching, we also demonstrate the non -reciprocal propagation of optical fields with isolation ratios above 10 dB. This work provides a robust and efficient acousto-optic platform, opening new opportunities for optical signal processing, quantum transduction, and non-magnetic optical isolation.
