Abstract

In this paper, a new approach to local terahertz time-domain spectroscopy (THz-TDS) using a microfabricated probe is reported. A microfabricated scanning near-field optical microscopy (SNOM) probe was assembled with a low-temperature-grown gallium arsenide (LT-GaAs) photoconductive antenna. The assembly was used as the THz emitter and local THz source. Another LT-GaAs antenna situated on the opposite side was used as the detector. A THz-TDS measurement using the microtabricated SNOM probe and photoconductive antenna was performed.
