Sub-hertz fundamental linewidth photonic integrated Brillouin laser [PDF]

Nature Photonics, 2018
Spectrally pure lasers, the heart of precision high-end scientific and commercial applications, are poised to make the leap from the laboratory to integrated circuits. Translating this performance to integrated photonics will dramatically reduce cost and

Spectral coherence, Part I: Passive-resonator linewidth, fundamental laser linewidth, and Schawlow-Townes approximation

Progress in Quantum Electronics, 2020
The degree of spectral coherence characterizes the spectral purity of light. It can be equivalently expressed in the time domain by the decay time τ or the quality factor Q of the light-emitting oscillator, the coherence time τ coh or length l coh of ...

Narrow-linewidth lasing and soliton Kerr microcombs with ordinary laser diodes [PDF]

Nature Photonics, 2018
Narrow-linewidth lasers and optical frequency combs generated with mode-locked lasers have revolutionized optical frequency metrology. The advent of soliton Kerr frequency combs in compact crystalline or integrated ring optical microresonators has opened
