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.

A dark point inside a beam of light should not be much of a traveler. Yet in a new experiment, some of those points appeared ...

Phase engineering of a wave function influences and determines the tendency and even results of physical processes, especially for efficient nonlinear optical frequency conversion. High conversion ...

a SHG intensity (I₂⍵) under phase mismatch and different APP phase-matching conditions with phase difference Δφ in a nonlinear crystal. The relative SHG intensities with light phase manipulation of ...
