Paper Abstract

We present the first steps for the validation of the concept of a new optically driven field emission cathode. The approach relies on the interaction of surface plasmons with vertically aligned multi-wall carbon nanotubes or metallic nanowire arrays. The objective is to modulate the field emission current by using the optical field component at the emitter apex through antenna coupling. Thanks to metallic surface gratings, surface plasmons will be generated and localized in the vicinity of nanoemitters to increase the interaction. First simulations and preliminary experimental measurements are presented jointly with perspectives for the wideband modulation of electronic beams up to THz.
