An adaptive-focus lens is a device that is capable of tuning its focal length by means of an
external stimulus. Numerous techniques for the demonstration of such devices have been …

Photonic crystal fibers (PCFs) are a special class of optical fibers with a periodic
arrangement of microstructured holes located in the fiber's cladding. Light confinement is …

In this work, a novel technique to create positive-negative tunable liquid crystal lenses is
proposed and experimentally demonstrated. This structure is based on two main elements, a …

There is an increasing need to control light phase with tailored precision via simple means
in both fundamental science and industry. One of the best candidates to achieve this goal …

We report an electrically tunable liquid crystal device that enables the generation of lenses
the diameters of which may be dynamically changed from sub-millimeter to multiple …

Microlenses and microlens arrays are one of the indispensable components in modern
optical systems ranging from imaging and beam sha** to polarization control and …

Plenoptic cameras have received a wide range of research interest because it can record
the 4D plenoptic function or radiance including the radiation power and ray direction. One of …

We demonstrate a technique to engineer cylindrical and Powell liquid crystal lenses with
positive or negative optical power. The device is based on two indium-tin-oxide electrode …

We demonstrated a 2D/3D switchable mobile display using a polarization-dependent
switching liquid crystalline polymeric (LCP) lens array film. In spite of short viewing distance …

The transmission electrode technique has been recently proposed as a versatile method to
obtain various types of liquid-crystal (LC) lenses. In this work, an equivalent electric circuit …
