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…
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…
Injection locking of GHz-frequency surface acoustic wave phononic crystal oscillator
Zichen Xi, Hsuan-Hao Lu, Jun Ji +4
Low-noise gigahertz (GHz) frequencies sources are essential for applications in signal processing, sensing, and telecommunications. Surface acoustic wave (SAW) resonator-based osci…
