Abstract

Drift-biased graphene enables strong nonreciprocal light-matter interactions. In this work, we show that applying two longitudinal DC bias orthogonal to each other permits to greatly manipulate the isofrequency contour of the surface in a nonreciprocal manner, allowing to dynamically steer and canalize one-way plasmons towards desired directions in the plane. Through a dedicated Green's function formalism that takes graphene's intrinsic nonlocality into account, we demonstrate that simply controlling two bias of just a few volts enables unprecedented flexibility to synthesize a large variety of nonreciprocal and broadband electromagnetic responses over a unique physical surface. Our findings may open intriguing applications in dynamic sub-diffractive imaging and sensing systems as well as in the routing and processing of surface plasmons.
