Domain control and periodic poling of epitaxial ScAlN
Fengyan Yang, Ding Wang, Ping Wang +3
ScAlN is an emerging ferroelectric material that possesses large band gap, strong piezoelectricity, and holds great promises for enhanced χ^{(2)} nonliearity. In this study, we dem…
III-Nitride nanophotonics for beyond-octave soliton generation and self-referencing
Xianwen Liu, Zheng Gong, Alexander W. Bruch +3
Frequency microcombs, successors to mode-locked laser and fiber combs, enable miniature rulers of light for applications including precision metrology, molecular fingerprinting, an…
Ultra-high-Q UV microring resonators based on single-crystalline AlN platform
Xianwen Liu, Alexander W. Bruch, Zheng Gong +6
Development of low-loss photonic components in the ultraviolet (UV) band will open new prospects for classical and quantum optics. Compared with other integrated platforms, aluminu…
