Augmented reality (AR) and virtual reality (VR) have the potential to revolutionize the
interface between our physical and digital worlds. Recent advances in digital processing …

Liquid crystals, compounds and mixtures with positive dielectric anisotropies are reviewed.
The mesogenic properties and physical chemical properties (viscosity, birefringence …

Liquid Crystal Devices are crucial and ubiquitous components of an ever-increasing number
of technologies. They are used in everything from cellular phones, eBook readers, GPS …

In this paper, we review liquid-crystal-on-silicon (LCoS) technology and focus on its new
application in emerging augmented reality (AR) displays. In the first part, the LCoS working …

A tunable-focus spherical lens using two flat substrates and inhomogeneous electric field
over a homogeneous liquid crystal (LC) layer is demonstrated. The top flat substrate has an …

We demonstrate a tunable focus liquid crystal (LC) lens by sandwiching a homogeneous LC
layer between a planar electrode and a curved electrode. The curved electrode which is …

Liquid crystals are a promising candidate for development of active plasmonics due to their
large birefringence, low driving threshold, and versatile driving methods. We review recent …

In this paper we review the state of the art in the field of liquid-crystal tunable guided-wave
photonic devices, a unique type of fill-once, molecular-level actuated, optofluidic systems …

We have analyzed the physical origins of the temperature gradient of the ordinary refractive
index (dn_o/dT) of liquid crystals. To achieve a large dn_o/dT, high birefringence and low …

A tunable-focus liquid lens using dielectrophoretic effect is demonstrated. When a voltage is
applied to a dielectric liquid droplet, the generated electric field inside the droplet is …
