Our devices modulate the intensity of a probe beam guided through a Mach-Zehnder interferometer (MZI) structure, under the illumination of an impinging THz wave. Golden bow-tie antennas fabricated along the waveguides, collect and tightly squeeze the THz radiation across their gap, greatly enhancing the THz-probe nonlinear interaction. We show that the probe intensity modulation reproduces the oscillations of the THz electric field established across the gaps of the metallic antennas.TechnologyPhysical Sciencestext::conference output::conference proceedings::conference paper
