Raman-Assisted Multiband Nonlinear Frequency-Conversion Network in a High-Q LTOI Microdisk
Zhifan Fang, Yuxuan He, Zhangning Pan +2
On-chip nonlinear frequency conversion offers a key route to broadband coherent light sources, but spanning telecom, visible, and ultraviolet wavelengths within a single resonator…
On-Chip Neodymium-Doped Lithium Niobate Microdisk Laser with Self-Induced Pulsing
Yuxuan He, Jiangwei Wu, Xiangmin Liu +5
Rare-earth-doped materials constitute the foundation of conventional solid-state lasers, but their bulk-crystal form is inherently incompatible with photonic integration, making it…
Erbium-doped lithium niobate waveguide amplifier enhanced by an inverse-designed on-chip reflector
Zhiwei Wei, Jiangwei Wu, Chengyu Chen +4
This study presents a 3.6-cm-long erbium-doped lithium niobate waveguide amplifier enhanced by an inverse-designed on-chip reflector. Integrating the reflector at the waveguide end…
3D Orbital Angular Momentum Nonlinear Holography
Feiyang Shen, Weiwen Fan, Yong Zhang +2
Orbital angular momentum (OAM), due to its theoretically orthogonal and unbounded helical phase index, has been utilized as an independent physical degree of freedom for ultrahigh-…
Cascaded multi-phonon stimulated Raman scattering near second-harmonic-generation in thin-film lithium niobate microdisk
Yuxuan He, Xiongshuo Yan, Jiangwei Wu +3
High-quality microresonators can greatly enhance light-matter interactions and are excellent platforms for studying nonlinear optics. Wavelength conversion through nonlinear proces…
Enhanced Nonlinear Frequency Conversion Bandwidth through Birefringence induced Mode Hybridization
Tingge Yuan, Jiangwei Wu, Xueyi Wang +3
On-chip quantum information network requires qubit transfer between different wavelengths while preserving quantum coherence and entanglement, which needs broadband up-conversion a…
