    Abstract

    We present the theoretical foundation of a novel concept for optical switching based on the conditional Faraday effect with electron spins in quantum dots (QDs). Calculations for light of wavelengths lambda = 1.3 mu m and lambda = 1.55 mu m show devices with active regions of a few hundred microns are possible. Case studies for both spherical and nonspherical QDs are considered, with calculations for the nonspherical case showing a 20% reduction in the required device length due to the lifting of the light and heavy hole band degeneracy.
