Abstract
Semiconductor quantum dots are often proposed as an ideal means to achieve non-linear interactions and photon switching in semiconductor integrated circuits. We examine here the use of the electron spin degree of freedom as a means to achieve a controllable quantum switching of single photons and trains of photons. We examine some types of spin-based quantum switches, and the design principles upon which a nanophotonic quantum switch that uses narrow band photons should be based.
