Invertible mapping between structured light and vector terahertz emission
Amirreza Sadeghpour, Daryoush Abdollahpour
Terahertz (THz) radiation provides a powerful platform for ultrafast spectroscopy, imaging, and communication, yet deterministic control over its spatial and polarization structure…
Formation of axially modulated plasma strings by filamentation of interfering femtosecond Bessel beams
Fatemeh Mansourimanesh, Amirreza Sadeghpour, Daryoush Abdollahpour
We numerically investigate the formation of axially modulated plasma strings through the filamentation of two interfering femtosecond Bessel beams. The constituent Bessel beams hav…
Filamentation of Femtosecond Vector Beams
Amirreza Sadeghpour, Daryoush Abdollahpour
We numerically study the filamentation of femtosecond vector beams with spatially varying polarization profiles in air. The vector beams include azimuthal, radial, and spiral cylin…
Flying doughnut terahertz pulses generated from semiconductor currents
Kamalesh Jana, Yonghao Mi, Søren H. Møller +5
The ability to manipulate the space-time structure of light waves diversifies light-matter interaction and light-driven applications. Conventionally, metasurfaces are employed to l…
