We present an experimental demonstration of a quantum dot (QD)-based plasmon emitter controllably integrated in designed patterns on a thin metal film. The generation of surface plasmons polaritons (SPPs) from optically excited QDs on a thin metal film is experimentally demonstrated. Long-range, low-dispersion, two-dimensional isotropic guiding, as well as efficient coupling of the SPPs are also shown. The realization of planar, low loss and efficient plasmon emitter-waveguide integration will offer further development of plasmon circuits.
