Introducing an optoplasmonic amplifier operating in visible range and generating raman signal internally with injection seeding

Resonant propagation of light is important for building novel light source and chip-scale optical interconnects. Here, we introduced an optoplasmonic amplifier which is operating in the visible range and generating Raman signal internally with injection seeding. We introduced the microspheres as a chain with different arrangements such as – single sphere; two spheres with equal and unequal sizes; three spheres with equal sizes and multi spheres with different sizes. We analyzed the effect of excitation and polarization with respect to different spheres and position of excitation. We noticed a shift of mode position with respect to different sizes of microspheres. We also had different kind of underlying substrates such as silicon nanopillar, polymer nanopillar, pyramid polymer and nanohole polymer and investigate the effect of these substrates on various chains of microspheres.
