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 ...

A team of researchers from the Center for Research and Innovation in Metamaterials at the University of Exeter and the Laser Processing Group at the Institute of Optics have presented in the journal ...

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 ...

QAM is used to achieve greater spectrum efficiency. This is accomplished by utilizing both the amplitude and phase components to modulate, or alter, the waveform. In this scenario, the QAM waveform ...
