  2. 1. Design, fabrication and characterization of plasmonic components based on silicon nanowire platform

    Author : Fei Lou; Lech Wosinski; Lars Thylén; Sebastian Lourdudoss; Anatoly Zayats; KTH; []
    Keywords : Planar integrated circuit; silicon photonics; plasmonics; subwavelength; directional coupler; polarization beam splitter; disk resonator; ring resonator; finite-difference time-domain; photonic crystal; electro-optic polymer; Purcell factor.;

    Abstract : Optical interconnects based on CMOS compatible photonic integrated circuits are regarded as a promising technique to tackle the issues traditional electronics faces, such as limited bandwidth, latency, vast energy consumption and so on. In recent years, plasmonic integrated components have gained great attentions due to the properties of nano-scale confinement, which may potentially bridge the size mismatch between photonic and electronic circuits.

    Abstract : The study of optical phenomena related to the strong electromagnetic response of noble metals (silver (Ag) and gold (Au) being most popular) over the last couple of decades has led to the emergence of a fast growing research area called plasmonics named after 'surface plasmons' which are electron density waves that propagate along the interface of a metal and a dielectric medium. Surface plasmons are formed by the coupling of light to the electrons on the metal surface subject to the fulfillment of certain physical conditions and they are bound to the metal surface.
