A tunable metasurface can control optical light in space and time, offering a path toward new ways of wirelessly and securely transmitting large amounts of data both on Earth and in space. It is a ...

For high-speed and large-capacity optical communication applications and improvement of accuracy in microwave generation and evaluation equipment TOKYO--(BUSINESS WIRE)--NTT Corporation (NTT) and ...

Devices made from certain materials can double the frequency of light. Programmable electrodes can tune this response to produce various light spectra. In the field of electronics, reprogrammable ...

A new, miniature laser source developed by applied physicists in the Harvard John A. Paulson School of Engineering and ...

A frequency comb is a spectrum of evenly spaced, phase-coherent laser lines, that acts like a ruler to measure the frequency of light with extreme precision. The dual-comb technique does not suffer ...

Laser frequency combs are valuable analytical tools for observing chemical phenomena or detecting the presence of particular species at low concentrations. The key to these applications is the ...
