A tunable double-channel narrowband terahertz filter integrated with parallel plate waveguide cavities is described. The filter is formed by machining two rectangular grooves into upper and bottom plates of parallel plate waveguide, respectively. Tuning is achieved by a relative lateral shift of two metal plates with rectangle grooves. Simulation results show that both the resonance frequency and...
Subwavelength confined terahertz waves propagating along a planar waveguide is successfully demonstrated via the integration between a diffraction metal grating and a plastic ribbon. The longest propagation distance and minimum confined range are, respectively, 50mm and λ/5, improving the deliverable range of spoof-surface-plasmon-polaritons.
Results on identification of liquids by a Josephson detector with a dielectric waveguide coupling are presented. Broadband and frequency-selective modes of the Josephson detector were used to extend a spectral bandwidth from 1 GHz to 500 GHz. A characterization of a liquid identifier was demonstrated for alcohols, acetone and water.
We have derived analytic expressions of bandwidth limitations of travelling-wave photodetectors (TWPDs) for only-output and both input/output impedance matching cases, without any approximations. Results are effective for design of TWPD for broadband terahertz photomixer.
It is shown that a continuous wave output power of 0.35 mW at 305 GHz can be generated by photomixing in a low temperature grown GaAs photoconductor using a metallic mirror Fabry-Pérot cavity. The output power is improved by a factor of about 100 as compared to the previous works on GaAs photomixers.
The Compact Advanced Terahertz Source (CATS) developed at ENEA during the past years has now been moved to a new bunker and upgraded for new application capabilities.
