A new, miniature laser source developed by applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Technical University of Vienna (TU Wien) could ...
Illustration of a Raman-suppressed, X-cut thin film lithium niobate racetrack microresonator used for microcomb generation. Harvard researchers have demonstrated a special type of optical frequency ...
Optical frequency combs—laser sources that emit evenly spaced colors of light—are foundational, ubiquitous tools for precision measurement, found in optical clocks, gas-sensing spectrometers, and ...
Researchers in Japan have developed a microwave-based plasma measurement system capable of simultaneously monitoring ...
There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...
A recent study published in the journal Nature Communications introduces a frequency-comb-referenced terahertz (THz) Fabry–Pérot interferometry platform for high-precision battery electrode metrology.
