Tunable solid-state terahertz-wave sources: New ideas and prospects
An idea to build a solid-state analog of vacuum travelling and backward wave tubes operating in the THz frequency range has long been discussed in the literature. Experiments directed to the realization of this idea using the radiative decay of grating-coupled two-dimensional (2D) plasmons in semiconductor heterostructures have been made since 1980, however the intensity of emitted radiation re...
متن کاملModeling and Design of Photoconductive and Superconductive Terahertz Photomixer Sources
Terahertz technology is a fast growing field with variety of applications in biology and medicine, medical imaging, material spectroscopy and sensing, monitoring and spectroscopy in pharmaceutical industry, security, and high-data-rate short-range communications. Among different terahertz sources, photomixers are potentially compact, low power consuming, coherent, low-cost, and tunable continuo...
متن کاملNano-antenna in a photoconductive photomixer for highly efficient continuous wave terahertz emission
We report highly efficient continuous-wave terahertz (THz) photoconductive antenna based photomixer employing nano-gap electrodes in the active region. The tip-to-tip nano-gap electrode structure provides strong THz field enhancement and acts as a nano-antenna to radiate the THz wave generated in the active region of the photomixer. In addition, it provides good impedance matching to the THz pl...
متن کاملPrecisely tunable continuous-wave terahertz source with interferometric frequency control.
We realized a tunable continuous-wave terahertz source with megahertz frequency resolution. The system is based on optical heterodyning of two near-infrared distributed feedback diode lasers, each laser being stabilized by electronic feedback from a low-finesse quadrature interferometer. The control loop permits precisely linear laser frequency scans over >1200 GHz, and a beat signal linewidth ...
متن کاملTerahertz-wave Parametric Sources
Terahertz waves are the electromagnetic radiation whose frequency ranges from millimeter waves to the far infrared, shown in Figure 1. While both sides of this range have had a long history of research and development, leading to already commercially available sources, detectors, meters, and many additional devices, the terahertz wave range is still in its infancy, representing the last unexplo...
