We present a photonics based Terahertz wireless communication system operating at 140 GHz and we achieve an error-free transmission of 6 Gbps over a link distance of 30 cm. We then design and demonstrate a practical model for the transmission of live uncompressed 4K video using the THz communication system. Finally, we study the video quality by analyzing each pixel frame by frame.
A combination of the low loss, low positive dispersion long THz fiber and a high negative dispersion short waveguide are used to demonstrate efficient dispersion compensation in a resultant fiber based THz transmission link. The transmission fiber is a graded index porous optical fiber featuring a non-uniform air-hole array with variable air-hole diameters and inter-hole separations for the dispersion...
Graded index porous fiber incorporating an air-hole array featuring variable air-hole diameters and inter-hole separations is proposed. We experimentally demonstrate smaller pulse distortion, larger bandwidth and higher excitation efficiency compared to fibers with uniform porosity.
A novel plasmonic THz fiber featuring two metallic wires in a porous dielectric cladding is studied for resonant sensing applications. In our design, introduction of even lossless analytes into the porous fiber core leads to significant changes in the modal losses, which is used as a transduction mechanism.
THz Bragg gratings were fabricated by using CO2 laser inscription. The simulated and experimental results demonstrate potential of such gratings in paper thickness monitoring, with experimental spectral sensitivities of ∼ −0.67 GHz / 10 µm.
A nanostructured chalcogenide-metal optical fiber is proposed. This hybrid nanofiber enables both very strong field confinement and extreme nonlinear light-matter interactions, much larger than a bare chalcogenide nanowire of comparable diameter.
Polymer optical fibers provide a cost-effective, design flexible, and industry-scalable platform for THz waveguides. We here review the latest developments in the design, fabrication and characterization of plastic-based optical fibers for the terahertz.
A new type of microstructured fiber for mid-IR is introduced. The chalcogenide microporous fiber allows extensive dispersion engineering that enables red-shifting the zero-dispersion point in the vicinity of CO2 laser lines and ultra-flat dispersion windows.
We demonstrate the operation of a novel class of narrow-band pass filters based on the revolutionary technology of non-proximity resonant tunneling in multi-core photonic band gap fibers.
Drawing of the PMMA/PS and PVDF/PC based, hollow all-polymer Bragg fibers are demonstrated. Effects of core collapse and multilayer nonuniformity on fiber transmission are considered. Non-newtonian dynamics modelling of Bragg fiber drawing is performed.
