P07–Analysis of a phase shifter based on a slot polymeric waveguide with liquid crystal cladding

Cornaggia F., Alam B., d’Alessandro A., Asquini R.

We numerically investigated a phase shifter based on a polymeric platform by using two different approaches. The device consists of a polymeric slot waveguide covered with an organic liquid crystal cladding, which is a promising configuration for the implementation of polymeric waveguide systems for computation, communication and sensing. Two different nematic liquid crystals have been […]

N06–Optical properties of a waveguide-fed plasmonic nano-array through approximated scattering theory

Alam B., Ferraro A., d’Alessandro A., Caputo R., Asquini R.

We analyze the optical scattering properties of an array of Au nano-cylinders fabricated upon an ion-exchanged waveguide. The integrated systems is considered for fluoroscopy and Raman spectroscopy. Absorption, scattering and extinction have been calculated through a combination of Finite Difference Time Domain (FDTD) method and scattering theory. While a portion of the excitation signal interacts […]
