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.

Most recently, among power electronics systems, the high-frequency (HF) isolated bidirectional dc–dc converter (IBDC) has received wide attention, and it has been widely implemented as an interface in ...

Continuous Phase Modulation (CPM) constitutes a family of constant-envelope digital modulation techniques in which symbol transitions occur with continuous phase trajectories. By maintaining a ...

Optical phase modulators are key components in optical communication, sensing, and signal processing systems. All-optical modulators, which modulate the phase or intensity of a light signal by 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 ...

Scientists in the Emirates have conceived a new space vector pulse width modulation method that reportedly reduces switching losses and increase efficiency in three-phase photovoltaic inverters. The ...
