Project Details


The objective of the present research project is to study light transmission by optical tunnelling in dielectric heteroguides with transversal dimensions below wavelength. The guide structures have two parts, one homogeneous and a second one consisting of an ordered nanopartícules array. The homogenous guide will be fabricated by electron beam lithography. Concerning the heterogeneous part, it will be fabricated from the following approaches: a) "top down" approach using electron beam lithography; b) "direct" manipulation of the nanopartícules by AFM; c) "bottom up" approach using biologic templates like functionalized oligonucleotides. Refernece linear heteroguides will be fabricates, more complicated geometries directly related to applications, like deflectors and beam splitters, will also be considered. The structural characterisation of the waveguides will be performed by electronic microscopy and AFM. The light transmission properties of the fabricates nanoestructures will be thoroughly investigated as a function of the nanopartícules geometry, base material and frequency of the incident light. We expect that the research performed within this project will contribute to a better understanding of light propagation through optical tunnelling in heteroguides with lateral dimensions below diffraction limit. Moreover this project will contribute to advance in the integration of "wireless" optical signal transmitters in optoelectronic devices and circuits. Finally, we will also address the use of biologic templates for the definition of ordered nanopartícules arrays
