Nanophotonics

Photonics or the control of light propagation and emission lies in the development of materials and structures whose complexity as continuously increased as a function of time. Today’s photonic components can combine both electron (quantum structures) and photon confinement.

In order to observe the light confined in the structures and thus to better understand the associated physical phenomena, new characterization techniques such as near field scanning optical microscopy and simulation tools need to be developed. Initially oriented toward the telecommunications industry, nowadays photonics potentially concerned numerous fields and industrial sectors, such as biology (photonic substrates), sensing (ultrasensitive sensors), energy production (high external yield solar cells), and lightning (ultra bright LEDs).

Results

Nanophotonics: Complex field mapping over the surface of a chain of gold elliptical nanocylinders integrated on silicon on isolator. Example of polymer-tipped optical fiber. SEM images of the probe apex without and with a carbon nanoprobe. Experimental shear-force controlled s-SNOM setup. AFM and SNOM image of a 3 mm wide ion-exchanged waveguide. Optical near-field photonic devices: SWIFTS integrated spectrometer. “All silicon” omnidirectionnal mirrors. Volume integral method (angular radiation pattern of NSOM probe coupled to a single nanoparticle), RCWA method (periodic array of gold nanowire integrated on glass), FDTD (plasmonic gap waveguide integrated on SOI).

Nanofocusing nanodevice

Des chercheurs ont obtenu la super-focalisation d’un champ lumineux dans un nano-dispositif, en intégrant une structure plasmonique, jouant le rôle de concentrateur de lumière, sur un guide d’ondes en silicium. Le confinement extrême de la lumière a pu être observé par une technique de microscopie à champ proche, développée au LNIO.
