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.…
Copper-impurity-free photonic integrated circuits enable deterministic soliton microcombs
Xinru Ji, Xurong Li, Zheru Qiu +5
Chip-scale optical frequency combs based on microresonators (microcombs) enable GHz-THz repetition rates, broad bandwidth, compactness, and compatibility with wafer-scale manufactu…
Arrayed waveguide gratings in lithium tantalate integrated photonics
Shivaprasad U. Hulyal, Jianqi Hu, Chengli Wang +3
Arrayed Waveguide Gratings (AWGs) are widely used photonic components for splitting and combining different wavelengths of light. They play a key role in wavelength division multip…
Full C- and L-band tunable erbium-doped integrated lasers via scalable manufacturing
Xinru Ji, Xuan Yang, Yang Liu +8
Erbium (Er) ions are the gain medium of choice for fiber-based amplifiers and lasers, offering a long excited-state lifetime, slow gain relaxation, low amplification nonlinearity a…
