Multi-pulse oscillations are prevalent phenomena observed in mode-locked lasers and nonlinear microresonators, where the short- and long-range interactions between nonlinear wavepackets give rise to ...

Rhythmic activity is ubiquitous in biological systems from the cellular to organism level. Reconstructing the instantaneous phase is the first step in analyzing the essential mechanism leading to a ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Complex modulation of optical fields (i.e., the control of light’s amplitude and phase) is vital to the ...

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 ...

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 ...
