I needed to test a UHF linear amplifier’s ability to deliver a low distortion AM signal output. Unfortunately, the output distortion requirement was better than the distortion limits of any commercial ...

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 ...

(Nanowerk News) Liquid-crystal (LC) phase modulators are widely used in optical systems because of their advantages of low power consumption, light weight, flexible bandwidth adjustment, and ...

The design strategy for terahertz metasurfaces capable of achieving spin-selective functionality through complex-amplitude modulation is systematically categorized into four distinct parametric ...
