Terahertz radiation — the band of the electromagnetic spectrum between microwaves and visible light — has promising applications in medical and industrial imaging and chemical detection, among other u...
Semiconductor-Superlattice Parametric Oscillator as a Subterahertz and Possible Terahertz Radiation Source
Subterahertz Possible Terahertz
2008/10/29
We describe the operation of a semiconductor-superlattice parametric oscillator (SPO) at a subterahertz frequency (near 300 GHz). The oscillator is driven by a microwave source (frequency near 100 GHz...
A polarization maintaining air-core polymer fiber for terahertz guiding is proposed. The bandgap repels modal power from the absorbent background polymers, resulting in significant suppression of moda...
Tunable terahertz Bloch oscillations in chirped photonic crystals
Tunable terahertz Bloch oscillations chirped photonic crystals
2015/8/11
We report simulations showing tunable terahertz oscillations of the electromagnetic field provided by the Bloch oscillations of a short photonic wave packet in a tilted band structure. The struc...
