Abstract
We propose and demonstrate a novel near-field probe, resonant at terahertz (THz) frequencies. A conical metal tip, with length 50-1000 μm is fabricated directly to the surface of a semiconductor surface, acting as a radially-polarized THz source. High field confinement is seen at the apex of the probe. The scattering efficiency is frequency dependent, and is likely related to the dipolar resonance along the length of the probe.
