ABSTRACT

This chapter discusses the use of polariton coupling in chains of nanoparticles (NPs) for resonant transmission of light for next-generation integrated circuits. It explores inter-particle coupling of simple two-dimensional structures to get physical insight into light transmission with resonantly coupled plasmonic particles. The chapter addresses the more complex three-dimensional particles on the silicon-on-insulator platform for on-chip integration. Nanocoupler is one of the most important passive components, through which light from the waveguide can be coupled into the dielectric nanoparticle (DNP) chain and vice versa. This device can be used for two purposes: to connect and route light between two types of photonic systems, namely the silicon photonics system and the DNP system, and to couple in-plane laser light source from the silicon waveguide into the DNP chain. Bend is one of the basic building blocks of photonic circuits.
