We describe the history, guiding mechanism, recent advances, applications, and future
prospects for hollow-core negative curvature fibers. We first review one-dimensional slab …

In this review, we describe dielectric properties of biological tissues and liquids in the
context of terahertz (THz) biophotonics. We discuss a model of the THz dielectric permittivity …

Infrared (IR) fibers offer a versatile approach to guiding and manipulating light in the IR
spectrum, which is becoming increasingly more prominent in a variety of scientific …

Lying between optical and microwave ranges, the terahertz band in the electromagnetic
spectrum is attracting increased attention. Optical fibers are essential for developing the full …

Over the past few decades, significant attention has been paid to the biomedical
applications of terahertz (THz) technology. Nowadays, THz spectroscopy and imaging have …

Terahertz waves, which lie in the frequency range of 0.1-10 THz, have long been
investigated in a few limited fields, such as astronomy, because of a lack of devices for their …

In this work we report two designs of subwavelength fibers packaged for practical terahertz
wave guiding. We describe fabrication, modeling and characterization of microstructured …

An in-fiber Mach–Zehnder Interferometer (MZI), based on hollow core fiber (HCF), for
measuring curvature is fabricated and experimentally demonstrated. The sensing part was …

The expanding role of refractive index measurement in many fields including chemistry,
biology and medicine, food industry, process control, and environmental monitoring, has led …

We study a 3D-printed hollow core terahertz (THz) Bragg waveguide for resonant surface
sensing applications. We demonstrate theoretically and confirm experimentally that by …
