The pulse scattering on the spiral notch does not prevent its partial recoupling in WGM.

The Sonogashira and Suzuki-Miyaura coupling reactions of N-alkoxyimidoyl bromides produced versatile ketoxime ethers in good to excellent yields. A one-pot reaction of the imidoyl bromides with arylboronic acid and allylmagnesium bromide to produce N-arylamines via Suzuki-Miyaura coupling followed by domino reaction involving sequential addition-eliminative rearrangement-addition reactions was developed.

These resonators behave like electromagnetic billiards with classical chaotic dynamic and dielectric boundary conditions. Comparisons of experiments, models and simulations show remarkable agreements between geometrical and wave approaches.

Photolithography and plasma etching processes are used to obtain the laser microcavities composed of a passive polymer doped with an active laser dye. These microlasers are essential in the study of open wave chaos physics for integrated optics applications.

One part of the structure is a long fiber optic feedback loop acting as a delay line. Different techniques have been introduced such as multiple loops in order to get very narrow spectral lines and large mode spacing. One of the problems due to long fiber loops is the size and the requirement of temperature control. In order to go toward integrated solutions it is also possible to introduce optical resonators instead of a delay line structure (as for classical electronic oscillators). But such resonators should present very high quality factor. In this paper we demonstrate solutions using resonators based on polymer materials such as PMMA-DCM. Structures such as micro-rings, micro-disks or stadium-shaped resonator have been realized at the laboratory. Quality factor of 600...

For optical microscopy, SPR phenomena may be taken advantage of to increase the signal- to-noise ratio so as to benefit to the spatial resolution in imaging applications. This paper presents a demonstration performed by scanning over a few scattering sources of sub micrometer size. In order to get a higher sensitivity studies for nanoparticles, a new development of radially polarized surface plasmon microscopy with two detection channels for linear reflection and epifluorescence, as well as a modulation detection scheme based on an annular disc, is reported.

Little attention has been paid to nonlinear optical microcavities whereby a prerequisite for quadratic effects is an in-plane transverse non-centrosymmetric orientation of the active part. We therefore propose optical poling as a more suitable means to induce such a configuration to a dye-grafted polymer medium than the traditional electric field thermal poling.

Les composants optiques intégrés, réalisés par une simple photolithographie en proche UV, présentent des facteurs de qualité allant jusqu’à 10 000 et des finesses supérieures à 10. Ces propriétés, en termes de performances en détection, assurent une bonne sensibilité, une faible limite de détection, une dynamique large et en font donc de bons candidats pour une application à la détection spécifique en surface de biomolécules. En plus, ces composants optiques intégrés en polymères sont parfaitement compatibles avec la microfluidique ce qui permet une excellente intégration optofluidique des biocapteurs.
