Abstract

In this paper, we report the design and fabrication of a scanning near-field optical microscopy (SNOM) probe with integrated zinc oxide photoconductive antennas for local terahertz (THz) spectroscopy. Photoconductive antennas are used as a THz pulse emitter and detector. A pyramidal tip with an aperture formed at the end of a silicon cantilever is used as an SNOM head.
