Baig, Sarwat E; Boland, Jessica L.; Damry, Djamshid A; Tan, Hark Hoe; Jagadish, Chennupati; Joyce, Hannah J; Johnston, Michael B


Progress in the terahertz (THz) region of the electromagnetic spectrum is undergoing major advances, with advanced THz sources and detectors being developed at a rapid pace. Yet, ultrafast THz communication is still to be realized, owing to the lack of practical and effective THz modulators. Here, we present a novel ultrafast active THz polarization modulator based on GaAs semiconductor nanowires arranged in a wire-grid configuration. We utilize an optical pump–terahertz probe spectroscopy...[Show more]
