Tailored profiles: The working principle of the new metalaser. The designed geometric phase profile is introduced to the metasurface by rotating the hole in each silicon nitride nanodisk. Then the ...

Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field rotates. The other comes ...

Light fields, as a form of electromagnetic waves, are characterized by fundamental parameters including intensity, phase, and polarization. Precise imaging of these three parameters is crucial for ...

The achromatic lens can focus the incident RCP and LCP light onto two distinct positions without chromatic aberration over a wide bandwidth. Broadband achromatic wavefront control, a cornerstone of ...
