Professor Kaoru Minoshima from the University of Electro-Communications and NEOARK Corporation have succeeded in prototyping a greatly improved magneto-optic effect (*1) measurement device as part of ...

Frequency combs are a Nobel-honored technology developed at NIST that are crucial to the latest experimental atomic clocks. "Nobody knew how to make an optical frequency synthesizer using little chips ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2022.210023 considers sub-femtometer-resolution absolute spectroscopy based on dual electro-optic frequency comb. Optical frequency ...

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 ...

Block diagram of Faraday effect measurement system using dual-comb spectroscopy. The signal comb (red line) passes through the sample and is superposed with the local comb (blue line). The vertical ...
