Abstract

SWIFTS (Stationary Wave Integrated Fourier Transform Spectrometer) is based on a very promising technology. It permits a drastic reduction of the size of spectrometers while conserving, even improving, their performances. We present the first attempt to realise a SWIFTS based on wave guides in glass operating in visible and near infra-red. Here, we present an original optical near-field detection in which nanowires of gold are used to directly sample the evanescent standing wave in the waveguide. With this first prototype we have been able to rebuild a spectrum with a resolution R=95.
