Abstract

Quantum dot coupling to plasmon nanowires may enable the development of all-optical nano-scale transistors, revolutionizing integrated photonics and information processing. However positioning between the quantum dot and the nanowire is problematic. We investigate lithographic plasmon waveguides as an alternative to colloidal nanowires. In particular, we investigate the suitability of a stripe plasmon waveguide – quantum dot system. The investigation uses a numerical procedure implemented in COMSOL Multiphysics. We show that a stripe waveguide is a suitable candidate for quantum dot - plasmon coupling, with similar efficiency to the nanowire for small waveguide cross-section. We also show that by decreasing the thickness of wire and stripe waveguides it is possible to double the spontaneous emission factor.
