Optical Excitations and Energy Transfer in Nanoparticle Waveguides
Abstract
The main objective of the present proposal was the comprehensive investigation of the high-quality optical modes bound to one-dimensional arrays of dielectric particles. Three particular goals were completed during the three years of the project: 1) Investigated the formation of high quality optical modes in linear chains of nanoparticles fabricated from different optical materials optical processing a relatively high refraction index. Found that when the refractive index exceeds 2 bound modes are always formed and their quality factor increases unlimitedly with increasing the number of particles. 2) Calculated quality factors for most bound modes in linear chain and circular array of particles and demonstrated that it increases exponentially with the number of particles in circular array and as the third power of the number of particles in linear chains. 3) Investigated interference of propagating guiding modes and demonstrated that these modes behave similarly to propagating electrons. All these goals were attained using multisphere Mie scattering formalism. Developed new codes, which are available online in the group website. The research has led to seven publications and one submitted paper, three invited and two contributed presentations in international conferences
