Resonance-enhanced integrated acousto-optic beam steering
Yue Yu, Qixuan Lin, Shucheng Fang +8
Optical beam steering is a key technology for free-space optical communication, sensing, and imaging. Mechanical beam steering systems suffer from limited scanning speed and bulky…
Motional-Current-Sensing Method and Simplified Closed-Loop Control Strategy for Piezoelectric-Resonator-based DC-DC Converters
Zhiyang Cao, Linbo Shao, Liyan Zhu
Piezoelectric resonators (PRs) have been seen as a competitive alternative to magnetic components. In PR-based converters, the motional current (in the LC series branch of the equi…
Nonlinear exceptional points in an integrated acoustic-wave oscillator for longwave infrared sensing
Linbo Shao, Zichen Xi, Zengyu Cen +8
Exceptional points (EP) featuring enhanced responsivity and rich dynamics have attracted extensive attentions in device developments and sensing applications. However, it remains d…
Magnet-Free Nonreciprocal frequency conversion using Sequential Temporal modulation: Theory and Simulations
Arya G. Pour, Jun Ji, Linbo Shao
Nonreciprocal conversion is essential for protecting sources and enabling unidirectional signal routing in photonic, phononic, electronics, and quantum systems, yet conventional im…
Microwave-acoustic-based isolated gate driver for power electronics
Liyang Jin, Zichen Xi, Joseph G. Thomas +6
Electrical isolation is critical to ensure safety and minimize electromagnetic interference (EMI), yet existing methods struggle to simultaneously transmit power and signals throug…
On-chip cavity electro-acoustics using lithium niobate phononic crystal resonators
Jun Ji, Joseph G. Thomas, Zichen Xi +7
Mechanical systems are pivotal in quantum technologies because of their long coherent time and versatile coupling to qubit systems. So far, the coherent and dynamic control of giga…
