The random fluctuations of an oscillator limit the precision of time and frequency measurements on which scientific and technological endeavours rely. The noise and long-term stability of the system ...

Blue Phase (BP) liquid crystals are self-assembled 3D photonic structures that uniquely combine optical isotropy with ultrafast electro-optical switching. Their cubic symmetry enables ...

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 ...

Liquid-crystal (LC) phase modulators are widely used in optical systems because of their advantages of low power consumption, lightweight, flexible bandwidth adjustment, and non-mechanical movements.

Signal modulation is one of the most basic and important concepts in the RF industry. It consists of using the variation of one or more parameters of a carrier signal to transmit information, ...
