THz beam focusing EXTENDED Paul Edit

چکیده
Illuminated by ultrashort optical pulses, large area multiplex terahertz semiconductor emitters that work on photoDember currents and Schottky potentials radiate a directional electromagnetic terahertz pulse which is controlled by the angular spectrum of the incident optical beam. Using the lens that focuses the incident near infra-red pulse, we have demonstrated THz emission focusing in free space and characterized a Gouy phase shift.

Measurement and calculation of the orientation dependence of terahertz pulse detection in ZnTe
We have performed measurements and calculations of the efficiency of terahertz (THz) detection in ZnTe as functions of the angle between the THz polarization and the crystal (001) axis of the angle between the THz polarization and the probe-beam polarization. We find that, for angles of 0° and 90° between the probe and THz polarization, the THz detection process is most efficient, whereas the c...
متن کاملTerahertz pulse propagation in the near field and the far field.
We present a detailed investigation of the propagation properties of beams of ultrashort terahertz (THz) pulses emitted from large-aperture (LA) antennas. The large area of the emitter is demonstrated to have substantial influence on the temporal pulse profile in both the near field and the far field. We perform a numerical analysis based on scalar and vectorial broadband diffraction theory and...
متن کاملAmplification of Transition-Cherenkov Terahertz Radiation of Femtosecond Filament in Air
The transition-Cherenkov terahertz (THz) radiation from a femtosecond laser filament in air is enhanced by 3 orders of magnitude in the presence of a longitudinal static electric field, while the radiation pattern and the polarization remain the same. An amplified longitudinal electron current inside the filament is responsible for this amplified THz emission. A plasma filament formed in air by...
متن کاملDesign and Characterization of 1.8-3.2 THz Schottky-based Harmonic Mixers
A room-temperature Schottky diode-based WM-86 (WR-0.34) harmonic mixer was developed to build high-resolution spectrometers, and multipixel receivers in the terahertz (THz) region for applications such as radio astronomy, plasma diagnostics, and remote sensing. The mixer consists of a quartz-based local oscillator (LO), intermediate-frequency (IF) circuits, and a GaAs-based beam-lead THz circui...
متن کاملFocused terahertz waves generated by a phase velocity gradient in a parallel-plate waveguide.
We demonstrate the focusing of a free-space THz beam emerging from a leaky parallel-plate waveguide (PPWG). Focusing is accomplished by grading the launch angle of the leaky wave using a PPWG with gradient plate separation. Inside the PPWG, the phase velocity of the guided TE1 mode exceeds the vacuum light speed, allowing the wave to leak into free space from a slit cut along the top plate. Sin...
