A fully integrated dispersion-managed femtosecond mode-locked laser
Xurong Li, Xuan Yang, Zheru Qiu +7
Femtosecond lasers underpin applications ranging from material processing to corneal surgery, while their regular pulse trains form optical frequency combs that have revolutionized…
Design of an Electrically Tunable Microtoroid for Frequency Selection of Polarization-Entangled Photons
Yichi Zhang, Enqi Ke, Judith Su
Encoding quantum information into discrete optical frequencies, or "frequency bins," uses different colors of light as additional information channels, allowing each photon to carr…
An integrated photonic millimeter-wave receiver with sub-ambient noise
Junyin Zhang, Shuhang Zheng, Jiachen Cai +6
Decades of progress in radiofrequency (RF) transistors and receiver frontends have profoundly impacted wireless communications, remote sensing, navigation, and instrumentation. Gro…
High-pulse-energy integrated mode-locked lasers based on a Mamyshev oscillator
Zheru Qiu, Jianqi Hu, Xuan Yang +9
Ultrafast lasers have unlocked numerous advances across science and technology: they enable corneal surgery, reveal chemical reaction dynamics, and underpin optical atomic clocks.…
