A waveguide for time-domain integration of THz pulses, comprising two wires extending from an input gap gto an output gap gat a tapering angle θ relative to a longitudinal axis, a gap of the waveguide decreasing linearly from the input gap gto the output gap g, wherein a size of the output gap is at least one order of magnitude smaller than a central wavelength λin a spectrum of the THz pulses, and a method for time-domain integration of THz pulses, comprising confining input THz pulses in the waveguide.

Method and system for time-domain integration of broadband terahertz pulses

A THz waveguide is described, comprising four conductive wires separated by an air gap, the THz waveguide allowing low-loss and dispersion-free propagation of a THz signal. The system for terahertz polarization-division multiplexing comprises at least two THz sources, a THz waveguide and a THz receiver, wherein said THz waveguide comprises four conductive wires separated by an air gap; THz pulses from the THz sources being coupled into the THz waveguide; the THz waveguide transmitting the THz pulses independently, the THz waveguide operating as a broadband polarization-division multiplexer. The method for terahertz polarization-division multiplexing, comprising multiplexing THz pulses from terahertz sources in free-space, coupling resulting multiplexed THz pulses into a THz waveguide comprising four conductive wires separated by an air gap; and demultiplexing the multiplexed THz pulses after propagation in the waveguide.
