Thin-film lithium niobate microresonator Raman lasing suppression methods and octave-spanning frequency combs. a, Thin-film lithium niobate microresonator Raman lasing suppression methods, including ...

Developed moore than a decade ago, the frequency comb technique has stimulated fundamental research as well as laser development and its applications because it gave rise to a major increase in the ...

Frequency combs are the rulers of light. By counting a wavelength’s many oscillations, they measure distance and time with extraordinary precision and speed. Since the discovery of optical frequency ...

The high-speed, 11-bit 349-series of PIN diode attenuators covers the 1.0 to 18 GHz range. Operating over octave frequency bands, the digitally controlled attenuators switch in less than 300 ns. Both ...

Sound-level measurements offer a conventional way to measure sound but do not contain frequency information, making it difficult to compare different sounds or vibration. Octave analysis filters the ...
