Broadband dispersion flattened porous core photonic crystal fiber for low loss THZ wave guiding
Terahertz (THz) radiation can be loosely defined in the frequency domain from 0.1 to 10 THz bands. It bridges the gap between microwave and optical wavelength and has already confined the researcher interest due its potential applications in spectroscopy, non-invasive imaging, biomedical sensing, a...

| description |
Terahertz (THz) radiation can be loosely defined in the frequency domain from 0.1 to 10 THz bands. It bridges the gap between microwave and optical wavelength and has already confined the researcher interest due its potential applications in spectroscopy,
non-invasive imaging, biomedical sensing, astronomy, security sensitive areas such as monitoring drugs, explosives or weapons in a non-destructive manner, hybridization of DNA and communications. A large number of the existing THz system are bulky and
rely on free space propagation due to the lack of low-loss transmission waveguides in the THz spectrum. Therefore, the investigation of low-loss, commercially feasible,
efficient and flexible waveguides for the exultant execution of THz scheme becomes
incapable of being disregarded. In this research, performance and properties of a porous
core dielectric fiber has been studied to find a suitable THz waveguide for
communication applications. A novel type of hybrid core porous fiber design has been
developed using TOPAS material. Propagation characteristics for different fiber core
porosity and core diameter have been studied with different percentages of core areas.
The effects of rotating the triangular air hole arrangements in the hybrid core region on
propagation have been studied for the proposed design. Simulation results show a flat
low EML of 0.0398±0.000416 cm
-1
from 1.5 to 5 terahertz (THz) range with negligible
confinement and bending loss with 17.89% core area of the total fiber. Also the reported
waveguide exhibits a near zero flat dispersion at 0.4±0.042 ps/THz/cm in the frequency
range from 1.25 to 5.0 THz. The reported novel design and innovative results with
special features have indicated the noteworthy potentiality of the proposed porous core
fiber as a reliable THz waveguide
for communication applications. |
