Coherent photon transport from spontaneous emission in one-dimensional waveguides

A two-level system coupled to a one-dimensional continuum is investigated. By using a real-space model Hamiltonian, we show that spontaneous emission can coherently interfere with the continuum modes and gives interesting transport properties. The technique is applied to various related problems with different configurations, and analytical solutions are given. (c) 2005 Optical Society of America.
