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 …

This paper reviews the subject of 3D printed hollow-core fibers for the propagation of
terahertz (THz) waves. Several hollow and microstructured core fibers have been proposed …

A novel highly sensitive porous core-photonic crystal fiber (PC-PCF) has been designed and
analyzed for detection of chemical analytes in the terahertz frequency range. The PC-PCF is …

In this paper, a novel partial type-b crystalline core with more compact cladding in
hexagonal packing photonic crystal fiber (CC-PCF)-based optical sensor has been …

Ethanol is widely used in chemical industrial processes as well as in the food and beverage
industry. Therefore, methods of detecting alcohol must be accurate, precise, and reliable. In …

The quality of fuel greatly affects the lifetime and smooth functioning of every petroleum
engine. To pursue higher profit, kerosene is mixed with petrol and diesel by many dishonest …

The optical properties of polymers and glasses useful for terahertz applications are
experimentally characterized using terahertz time-domain spectroscopy (THz-TDS). A …

In recent years, photonic crystal fiber (PCF) in the THz regime has gained popularity very
swiftly for wave guidance and sensing applications. The optical properties of PCF can be …

Detection of blood is very crucial as well as sensitive due to its importance in human body. In
this manuscript, a hollow core Topas-based photonic crystal fiber (PCF) biosensor is …

We present a novel strategy for designing a highly birefringent photonic crystal fiber (PCF)
with near zero flattened dispersion properties by applying elliptical air holes in the core area …
