Chip-based f-2f interferometry in periodically tapered lithium niobate nanophotonic waveguides
Xinyan Chi, Ruoao Yang, Zhiyuan Li +4
Nanophotonic supercontinuum generation offers a practical route to chip-based f-2f interferometry by leveraging coexisting chi(2) and chi(3) nonlinearities. In conventional uniform…
Recursive Inverse Design Enables Hyper-spectral Photonic Integrated Circuits
Hao He, Zengji Tu, Yuanlei Wang +9
Spectrum manipulation is central to photonic systems, where advanced computing and sensing applications often demand highly complex spectral responses to achieve high throughput. C…
Practical 1-um GHz fiber comb on silica-based platform
Ruoao Yang, Xingang Jin, Ya Wang +9
We present a fully stabilized 1-GHz Yb-fiber laser frequency comb built on silica substrates, utilizing "optical cubes" to house all optical components, ensuring long-term stabilit…
Compact 780 nm Rb Optical Clock
Zhendong Chen, Tianyu Liu, Qiaohui Yang +8
We demonstrated a compact 780 nm rubidium optical clock, which includes an optical frequency standard and an optical frequency comb, with an optical volume of 11.6 liters. Unlike t…
GHz fundamental mode-locking of a highly integrated Er-doped all-fiber ring laser
Maolin Dai, Bowen Liu, Yifan Ma +4
High repetition rate ultrafast fiber lasers are important tools for both fundamental science and industry applications. However, achieving over GHz repetition rate in passively mod…
783-MHz fundamental repetition rate all-fiber ring laser mode-locked by carbon nanotubes
Maolin Dai, Bowen Liu, Yifan Ma +5
We demonstrate a 783-MHz fundamental repetition rate mode-locked Er-doped all-fiber ring laser with a pulse width of 623 fs. By using carbon nanotubes (CNT) saturable absorber (SA)…
