I am interested in the study and applications of electromagnetic resonance phenomena in wavelength-scaled structured components. The electromagnetic modes are either guided modes in dielectric structures, or cavity modes, or surface plasmons in metallic structures (plasmonics). The application fields are, among others, telecommunications (spectral filtering, single photon emission…), bio-photonics (molecule detection…), the Environment (gas spectroscopic analysis…), lasers (10µm sources…). I am studying especially resonant gratings (diffraction grating etched on top of a planar waveguide) for narrow-band filtering (ANR-PNano project FOREAC) and metallic nano-holes for single molecule detection.
