Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

This study demonstrates a compact optical modulation platform that enables real-time, high-resolution spectroscopy using sub-MHz interleaved combs generated via chip-scale acousto-optic phase ...

Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...
