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 ...

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 ...

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 ...

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 ...

Focused laser-like light that covers a wide range of frequencies is highly desirable for many scientific studies and for many applications, for instance, quality control of manufacturing semiconductor ...

Editor’s Note: This DI is a two-part series. Part 1 shows how to make an oscillator with a pitch that is proportional to a control voltage. Part 2 shows how to modify the circuit for use with higher ...

GA, UNITED STATES, September 4, 2024 /EINPresswire / -- Since the early 2000s, optical frequency combs have had a major impact on science and technology. Miniaturization onto photonic chips is ...
