Abstract

We theoretically investigate the generation of electric currents in quantum rings resulting from the optical excitation with twisted light. Our model describes the kinetics of electrons in a two-band model of a semiconductor-based mesoscopic quantum ring coupled to light having orbital angular momentum (twisted light). We find the analytical solution, which exhibits a “circular” photon-drag effect and an induced magnetization, suggesting that this system is the circular analog of that of a bulk semiconductor excited by plane waves. For realistic values of the electric field and material parameters, the computed electric current can be as large as µA; from an applied perspective, this opens new possibilities to the optical control of the magnetization in semiconductors.

(color online) Orbital angular momentum: population-based contribution for l=1 in dotted (blue) and for l=5 in dashed (black) lines, and coherence-based contribution for l=1 in full (red) line. The ordinate is given in values of h̄, the OAM of a single electron orbiting the QRing. The parameters for the ring are: GaAs semiconductor QRing, number of electrons excited M=100, r 0=1µm; for the TL-beam pico-seconds pulsed beam: wavelength λ=300nm, ω=21015s-1, average electric field per pulse 5107V/m, detuning 0.06eV. The Rabi frequency is ��⋍ 1014s-1.
