Optical manipulation of quantum dot excitons strongly coupled to photonic crystal cavities
In this paper, we review some recent cavity quantum electrodynamic (CQED) experiments with single quantum
dot exciton coupled to photonic crystal cavities, performed in our group. We show how the coupled quantum-dot/cavity system can be used to modulate light with at a very fundamental level with very low power and
discuss some applications of these low power modulators
Theory of Electro-optic Modulation via a Quantum Dot Coupled to a Nano-resonator
In this paper, we analyze the performance of an electro-optic modulator based
on a single quantum dot strongly coupled to a nano-resonator, 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.Comment: 9 pages, 7 figure
