Lidar imaging systems are one of the hottest topics in the optronics industry. The need to
sense the surroundings of every autonomous vehicle has pushed forward a race dedicated …

In addition to displays, liquid crystals (LCs) have also found widespread applications in
photonic devices, such as adaptive lens, adaptive optics, and sensors, because of their …

A tunable-focus liquid crystal microlens array is demonstrated and characterized. Using two-
photon polymerization based direct-laser writing, a polymerized microlens array is fabricated …

Nematic liquid crystals of achiral molecules or racemic mixtures of chiral ones form flat films
when suspended in submillimeter size grids and submerged under water. Recently, it has …

We report a rapid nano-imprinting technique to pattern the liquid crystal alignment of a
Pancharatnam–Berry phase microlens array. Through implementing a single-side aligned …

The fabrication of micro/nanostructure arrays on nickel or nickel alloy surfaces is still a
challenge because of the high hardness and low thermal conductivity. Motivated by this, this …

We fabricate 100% fill factor microlens arrays (MLAs) using femtosecond laser direct writing.
The array consists of periodical hexagonal plano-convex microlens units with a diameter of …

A novel beam steering angle expander is demonstrated by cascading two polymeric liquid
crystal polarization lenses with different diopters. The lens module performs as a planar …

We report a novel microlens array with different curvature unit lenses (MLADC) fabricated
with femtosecond laser direct writing technology. The MLADC consisted of hexagonal …

We demonstrate a photo-switchable and photo-tunable microlens based on chiral liquid
crystals doped with an azobenzene chiral dopant immersed in water. A bi-stable microlens …
