1-Mbps Twin-Field Quantum Key Distribution over 200 km Using Independent Dissipative Kerr Solitons
Hao Dong, Tian-Jiao Zhang, Yan-Wei Chen +10
Twin-field quantum key distribution (TF-QKD) dramatically enhances the secure key rate (SKR) over inter-city distances through its square-root scaling. Further improvements in aggr…
Kramers-Kronig causality in integrated photonics: The spectral tension between ultraviolet transition and mid-infrared absorption
Yue Hu, Zhenyuan Shang, Chenxi Zhang +12
Dispersion engineering via geometric confinement is essential to integrated photonics, enabling phenomena such as soliton microcombs, supercontinua, parametric oscillators, and ent…
Universal Kerr-thermal dynamics of self-injection-locked microresonator dark pulses
Shichang Li, Kunpeng Yu, Dmitry A. Chermoshentsev +8
Microcombs, formed in optical microresonators driven by continuous-wave lasers, are miniaturized optical frequency combs. Leveraging integrated photonics and laser self-injection l…
Hybrid-integrated dark-pulse microcombs towards visible light spectrum
Jinbao Long, Xiaoying Yan, Sanli Huang +9
Leveraging hybrid integration, we demonstrate dark-pulse formation at 780-nm wavelength band in integrated SiN microresonators driven by high-power AlGaAs-based chip-scale…
A high-resolution microresonator-frequency-comb spectrometer
Ruocan Zhao, Bin Yang, Chuan Huang +10
Spectral analysis is one of the most powerful technologies for studying and understanding matter. As the devices for spectral analysis, spectrometers are widely used in material de…
A chip-based optoelectronic-oscillator frequency comb
Jinbao Long, Zhongkai Wang, Huanfa Peng +14
Microresonator-based Kerr frequency combs ("Kerr microcombs") constitute chip-scale frequency combs of broad spectral bandwidth and repetition rate ranging from gigahertz to terahe…
