Metasurfaces can manipulate the amplitude and phase of electromagnetic waves, offering applications from antenna design and cloaking to imaging and communication. Temporal and non-linear metasurfaces ...

An important application for photonic-mm-wave phased arrays is their deployment in remote radio heads (RRH) of high data-rate networks where data processing and modulation is centralized at a baseband ...

Since the conception of the laser frequency comb in the late 1990s, it has revolutionized the precise measurement of frequency and time. Beyond their initial use in optical clocks and precision ...

Sometimes technology advances through wholesale change, like when cellular phone networks switched from analog to digital signals, and sometimes there is incremental change, like when CD players ...

A team of researchers at the University of California, Los Angeles (UCLA) has introduced a novel framework for monitoring structural vibrations using diffractive optical processors. This new ...
