Semiconductor nanowires in terahertz photonics: From spectroscopy to ultrafast nanowire-based devices

Abstract

Nanowires show unique promise for a multitude of optoelectronic devices, ranging from solar cells to terahertz (THz) photonic devices. Here, we discuss how THz spectroscopy is guiding the development of such nanowire-based devices. As an example, we focus on developing nanowire-based THz polarization modulators.
