Journal ArticleDOI
3D printed hollow-core terahertz optical waveguides with hyperuniform disordered dielectric reflectors
TL;DR: In this article, a hollow core THz waveguide with hyperuniform disordered reflectors is proposed, fabricated, and characterized, and the results confirm that proposed waveguide exhibit sizable photonic band gaps (20%) even when relatively low refractive index contrast used (resin/air).
Journal ArticleDOI
All-dielectric metamaterial analogue of electromagnetically induced transparency and its sensing application in terahertz range.
TL;DR: Theoretical investigations show that EIT effects in the authors' metamaterial are achieved by hybridizing two bright modes in the same unit cell, which are aroused by the excitation of magnetic moments, which guarantees potential applications in in situ chemical and biological sensing.
Journal ArticleDOI
Graded index porous optical fibers – dispersion management in terahertz range.
TL;DR: Graded index porous fiber incorporating an air-holes array featuring variable air-hole diameters and inter-hole separations is proposed and experimentally demonstrates smaller pulse distortion, larger bandwidth and higher excitation efficiency compared to fibers with uniform porosity.
Journal ArticleDOI
Analog signal processing in the terahertz communication links using waveguide Bragg gratings: example of dispersion compensation.
TL;DR: The results confirm single mode guidance, relatively high coupling efficiency, as well as large negative group velocity dispersions in the range of several -100's ps/(THz · cm) in the vicinity of 0.14THz, suitable for compensating positive dispersion incurred in the THz wireless links or fiber-assisted THz interconnects for signals of several-GHz bandwidth.
Journal ArticleDOI
Ultrafast control of slow light in THz electromagnetically induced transparency metasurfaces
TL;DR: In this paper, the authors demonstrate ultrafast optical control of slow light in the terahertz (THz) range by combining the electromagnetically induced transparency (EIT) metasurfaces with the cut wire made of P+-implanted silicon with short carrier lifetime.
