THz transient photoconductivity with near-field detection

Research output: Chapter in Book/Report/Conference proceedingConference contributionAcademicpeer-review

Abstract

We demonstrate a novel technique that enables the sub-diffraction near-field study of photo-excited structures probed with broadband THz radiation. As a proof-of-concept this system measures sub-ps temporal dynamics of photoexcited carriers in a thin film of GaAs with a spatial resolution of 60 μm (λ/10 at 0.5 THz peak intensity).
