We propose and implement a technique for arbitrary pattern fabrication in liquid crystal (LC)
alignments and local polarization control for light wavefront. A micro-lithography system with …

We experimentally demonstrate and theoretically analyze high Q-factor (~ 107) capillary-
based optical ring resonators for non-contact detection of air-coupled ultrasound. Noise …

The polarization independence of liquid crystal gratings with alternate orthogonal aligned
regions is theoritically studied and demonstrated by means of photoalignment technique …

Optics, playing an ever‐important role in life, is develo** toward miniaturization and
integration. Particularly, the field programming of integrated optics will benefit its functionality …

We propose and experimentally demonstrate a novel electric field intensity sensor by using
a tilted fiber Bragg grating (TFBG) interacting with liquid crystal. The TFBG is surrounded by …

A blue‐phase liquid‐crystal grating is proposed by applying a vertical electric field with
lateral periodic distribution. Simulation on electric‐field distribution was also carried out, the …

In present article, we disclose a fast switchable grating based on nematic liquid crystals. A
fine striped electrode has been exploited to generate the grating profile and a driving …

Optical fiber evanescent-wave sensors in which a portion of the fiber cladding has been
removed are attractive components for chemical and biological applications [1, 2]. Like all …

The orientation change of nematic liquid crystal (NLC) has been the essential mechanism
for various high sensitive sensors. In this paper, a side-polished fiber (SPF) is proposed to …

Lenticular array products have experienced a growing interest in the last decade due to the
very wide range of applications they can cover. Indeed, this kind of lenses can create …
