Lithium-Niobate-Based Frequency-Agile Integrated Lasers

Tobias Kippenberg, Junqiu Liu, Rui Ning Wang, Guanhao Huang, Anat Siddharth, Mikhail Churaev, Viacheslav Snigirev, Grigorii Likhachev

We demonstrate narrow- linewidth ultrafast tunable integrated lasers based on heterogeneously integrated thin-film lithium niobate on ultra-low loss silicon nitride integrated photonic circuits. Using self-injection locking of a hybrid microresonator, we a ...

Low-noise frequency-agile photonic integrated lasers for coherent ranging

Tobias Kippenberg, Junqiu Liu, Rui Ning Wang, Johann Emmeram Riemensberger, Wenle Weng, Jijun He, Anat Siddharth, Andrey Voloshin, Viacheslav Snigirev, Vladimir Shadymov

Stable and tunable integrated lasers are fundamental building blocks for applications from spectroscopy to imaging and communication. Here the authors present a narrow linewidth hybrid photonic integrated laser with low frequency noise and fast linear wave ...

Sub-MHz linewidth, FMCW photonic integrated blue laser

Tobias Kippenberg, Anat Siddharth, Xinru Ji

We demonstrate for the first time a frequency-modulated continuous wave photonic integrated blue laser with sub-MHz linewidth. The laser exhibits frequency excursion greater than 900 MHz at up to 1 MHz triangular chirp rate with a nonlinearity of less than ...
