Abstract

We theoretically investigate the interaction of a single quantum dipole with the modes of a fiber-coupled semiconductor waveguide. Through a combination of tight modal confinement and phase-matched evanescent coupling, we predict that approximately 70 % of the dipole's emission can be collected into a single mode optical fiber. Calculations further show that the dipole strongly modifies resonant light transmission through the system, with over an order of magnitude change possible for an appropriate choice of fiber-waveguide coupler geometry.
