2D Optical Beam Scanning using Integrated Acousto-Optics and a Frequency Comb
Shucheng Fang, Qixuan Lin, Fengyan Yang +5
Optical beam steering is an essential technology for free-space optical communication, reconfigurable optical networks and quantum information systems. Yet conventional steering me…
Tunable Mixed Parity Spin Splittings in Altermagnets
Yue Yu
Momentum-dependent spin splitting and its relation to inversion () and time-reversal () symmetries are central to nonrelativistic spintronics. Representative examples include…
Temperature-dependent acoustic loss at microwave frequencies in thin-film lithium niobate
Qixuan Lin, Yue Yu, Alejandra Guedeja-Marrón +7
Thin-film lithium niobate (TFLN) has emerged as a versatile platform for phononic and photonic devices with applications ranging from classical signal processing to quantum technol…
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…
Optical multi-beam steering and communication using integrated acousto-optics arrays
Qixuan Lin, Shucheng Fang, Yue Yu +4
Optical beam steering enables optical detection and imaging in macroscopic or microscopic scales and long-range communication over free space. It underpins numerous optical applica…
