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.
