Add drop multiplexers for terahertz communications using two-wire waveguide based plasmonic circuits
Yang Cao, Kathirvel Nallappan, Guofu Xu +1
Terahertz (THz) band is considered as the next frontier in wireless communications. The emerging THz multiplexing techniques are expected to dramatically increase the information c…
8 x 8 Terahertz Photoconductive Antenna Array and Parallelized Signal Acquisition System for Fast Spatially Resolved Time Domain Spectroscopy
R. Henri, K. Nallappan, D. S. Ponomarev +4
Terahertz (THz) technology is promising in several applications such as imaging, spectroscopy and communications. Among several methods in the generation and detection of THz waves…
Microstructured fiber links for THz communications and their fabrication using infinity printing
Guofu Xu, Kathirvel Nallappan, Yang Cao +1
In this work, a novel infinity 3D printing technique is explored to fabricate continuous multi-meter-long low-loss near-zero dispersion suspended-core polypropylene fibers for appl…
Dispersion Limited versus Power Limited Terahertz Transmission Links Using Solid Core Subwavelength Dielectric Fibers
Kathirvel Nallappan, Yang Cao, Guofu Xu +3
In this work, we present an in-depth experimental and numerical study of the short-range THz communications links that use subwavelength dielectric fibers for information transmiss…
Super-resolution Orthogonal Deterministic Imaging Technique for Terahertz Subwavelength Microscopy
Hichem Guerboukha, Yang Cao, Kathirvel Nallappan +1
Terahertz subwavelength imaging aims at developing THz microscopes able to resolve deeply subwavelength features. To improve the spatial resolution beyond the diffraction limit, a…
3D-printed Terahertz Photonic Bandgap Waveguide-based Fluidic Sensor
Yang Cao, Kathirvel Nallappan, Hichem Guerboukha +2
A Bragg waveguide-based resonant fluidic sensor operating in THz band is studied. A fused deposition modeling 3D printing technique is employed to fabricate the sensor where the li…
