Abstract
A quantum EIT-based optical switch includes a first waveguide, linear or nonlinear, a separate nonlinear waveguide evanescently coupled to the first waveguide, and a pump coupled to the nonlinear waveguide. A quantum STIRAP-based optical transduction device, which includes an auxiliary, intermediate spectral state for the quantum signal that aids efficient transduction of the quantum signal from the input spectral state to the output spectral state in a single device.
