Airy beams exhibit intriguing properties such as nonspreading, self-bending, and self-
healing and have attracted considerable recent interest because of their many potential …

Liquid crystal q-Airy-plates with director distributions integrated by q-plates and polarization
Airy masks are proposed and demonstrated via the photoalignment technique. Single/dual …

We demonstrate a new type of circular Airy beam, the azimuthally modulated circular
superlinear Airy beam, generated by utilizing a diffraction element, whose transmission …

The digital optical phase conjugation (DOPC) technique is being actively developed for
optical focusing and imaging through or inside complex media. Due to its time-reversal …

Smart windows, which can provide comfortable indoor conditions for cars or buildings and
