Theory of electro-optic modulation via a quantum dot coupled to a nano-resonator
Abstract
In this paper, we analyze the performance of an electro-optic modulator based on a single quantum dot strongly coupled to a nanoresonator, where electrical control of the quantum dot frequency is achieved via quantum confined Stark effect. Using realistic system parameters, we show that modulation speeds of a few tens of GHz are achievable with this system, while the energy per switching operation can be as small as 0.5 fJ. In addition, we study the non-linear distortion, and the effect of pure quantum dot dephasing on the performance of the modulator.
