This paper presents a review of the radio frequency thin-film lithium niobate (LiNbO 3) based
acoustic microsystems. Thanks to their high electromechanical coupling (k 2), low loss, and …

Since the advent of the laser, acousto-optic modulators have been an important tool for
controlling light. Recent advances in on-chip lithium niobate waveguide technology present …

Acoustic devices play an important role in classical information processing. The slower
speed and lower losses of mechanical waves enable compact and efficient elements for …

We present a piezoelectric transducer in thin-film lithium niobate that converts a 1.7-GHz
microwave signal to a mechanical wave in a single mode of a 1-μ m-wide waveguide. We …

Lithium niobate (LNO) is a well established material for surface acoustic wave (SAW)
devices including resonators, delay lines and filters. Recently, multi-layer substrates based …

We report direct visualization of gigahertz-frequency acoustic waves in lithium niobate
phononic circuits. Primary propagation parameters, such as the power flow angle and …

In this work, we present gigahertz low-loss unidirectional acoustic focusing transducers in
thin-film lithium niobate. The design follows the anisotropy of fundamental symmetric (S0) …

Electronic devices exploiting acoustic vibrations are ubiquitous in classical and quantum
technologies. Central to these devices is the transducer, which enables the exchange of …

This paper proposes a class of high-performance surface acoustic wave (SAW) waveguides
based on AlN-on-SiC substrates. Under the existing crystal growth and processing …

Integrated optical tunable filters are key components for a wide spectrum of applications,
