High Efficiency Photovoltaic and Plasmonic Devices

Abstract

This work focuses on laser diodes (LDs) that utilize the new silicon-germanium-tin technology capable of true monolithic integration on silicon. These miniature waveguided LDs would be key "enablers" for chip-scale networks of group IV active and passive components. In this work we have developed a rigorous analytical approach to the field enhancement in complex systems of coupled metallic nanoparticles. Our analysis confirms the fact that more complex metallic nanostructures do offer advantage over the single nanoparticles and provides a simple "engineering" explanation in which the large enhancement is achieved in a smaller "cavity" mode that is coupled to a larger "antenna" mode.
