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 …

Bessel beams have multiple applications owing to their propagation-invariant properties,
including particle trapping, optical coherence tomography, and material processing …

In this research work we demonstrated negative axicon optical fiber tip filled with
Polydimethylsiloxane (PDMS) as a sensor platform for volatile organic gases detection at …

This work demonstrates an interferometric technique to estimate the reflected powers from
dielectric interfaces and the reflection coefficient using the Fresnel equation for …

We demonstrate a non-contact trapping of a yeast cell by an optical fiber probe with a micron-
size concave cavity both theoretically and experimentally. We fabricate the optical fiber tip …

In this article, we demonstrate the packaging of an optical fiber negative axicon probe
generating Bessel beam and its application in the measurement of refractive index (RI) of …

Many bioimaging studies, including those in engineered tissue constructs, intravital
microscopy in animal models, and medical imaging in humans, require cellular-resolution …

For the most popular method of scan formation in Optical Coherence Tomography (OCT)
based on plane-parallel scanning of the illuminating beam, we present a compact but …

Clinical diagnosis increasingly relies on obtaining visualization images through optical
coherence tomography (OCT) endoscopes with small-volume, large focusing depth, and …

In this work, a common-path optical coherence tomography (OCT) system is demonstrated
for characterizing the tissue in terms of some optical properties. A negative axicon structure …
