Paper Abstract

Here we present a plasmonic memristor operated at the telecommunication wavelength with compact size (0.61 μm), and high extinction efficiency (4.6 dB/μm). The plasmonic memristor consists of a triangle-shaped metal taper mounted on the top of a Si waveguide with rational doping in the area below the apex of the taper. This device can achieve vertical coupling of light energy from the Si waveguide to the plasmonic region and at the same time concentrates the plasmon to the apex of the metal taper. Moreover, the area with concentrated plasmon is overlap with that where the memristive behavior occurs due to the formation/removal of the metallic nanofilament. As a result, the highly distinct transmission induced by the switching of the plasmonic memristor can be achieved due to the maximized interaction between the plasmon and the filament.
