Testo completoThis thesis deals with femtosecond pulse shaping and temporal characterization. The originality of the work resides in the proposed approach in which metrology plays the essential role. The thesis' first part addresses the problem of the theoretical and experimental limitations of short pulse shaping via an Acousto-Optic Programmable Dispersive Filter (AOPDF). A detailed and accurate analysis of the device was performed by spectral interferometry to determine its precision. An essential step in this work consisted in characterizing the precision available through spectral interferometry beforehand. A systematic study of the precision of first to fourth-order polynomial phases generated with the AOPDF was then undertaken. The main factors responsible for the observed discrepancies between the programmed and applied phases are presented and discussed. A method is proposed to correct them. The second part of the thesis is devoted to the study of three different pulse characterization techniques: a reference one, " Spectral Phase Interferometry for Direct Electric-field Reconstruction " (SPIDER) and two others developed during the thesis: " Local Spectral Compression " (LSC) and " Self-Referenced Spectral Interferometry " (SRSI). The precision of the measurement of quadratic and cubic phases generated with the AOPDF was determined for each method. All of these precisions were compared with each other. Pulses were also compressed to their Fourier limit using a feedback loop between the LSC device and an AOPDF first, and secondly the SRSI device and an AOPDF. Finally, each technique's advantages and limitations are discussed

Testo completoAt nanometer scale, the metallic particles exhibit new optical properties related to the surface plasmon resonance phenomenon. A plasmon resonance is a collective and coherent oscillation of the conduction electrons at a metallic nanoparticle surface under an external electromagnetic field. The resonance wavelength and the spatial distribution of the associated electromagnetic field depend on the nanoparticle characteristics (size, shape and chemical nature), the surrounding dielectric medium and the illumination geometry.The excitation of surface plasmons generates local electromagnetic fields of high intensity located at specific points of the nanoparticle called "hot spots". The light is miniaturized and confined in sub-wavelength areas (<20 nm). The ability to produce and control hot spots holds great promise for a large range of applications from information technology to renewable energies and biomedicine. This thesis highlights the possibility of generating and manipulating hot spots in nanostructures throughout the particle geometry or/and the configuration and wavelength of the exciting light. To do this, the optical response of various metallic nano-objects of different geometries and sizes, taken individually: cube, prism ... or in groups: dimer, chain ... are studied by PhotoEmission Electron Microscopy (PEEM), a non-intrusive and high resolution (20 nm) mapping technique allowing a selective addressing of plasmons modes. In addition to this experimental investigation, the search for a specific optical near-field distribution is also carried out using group theory. We developed an original theoretical method allowing to predict in a few minutes the plasmonic response of a 2D or 3D particle, of finite or infinite symmetry, alone or in dimer, from the object and exciting field symmetries. In parallel, numerical simulations using the Boundary Element Method (BEM) have been carried out

Testo completoNear-field optical forces arise from evanescent electromagnetic fields, such as in the near-field of photonic waveguides and nanocavities where light is highly confined. These contactless forces can be advantageously used to trap and manipulate micro- and nano-objects in solution. This thesis aims at studying these intriguing interactions and investigating their potential applications. The first chapter is an introduction to the fields of colloidal systems and optical trapping, more especially using near-field optical forces. The second chapter presents the experimental setup and the process used to fabricate optofluidic chips with microfluidic channels. The trapping potential experienced by 2 $µm$, 1 $µm$, and 500 $nm$ microbeads at the surface of a photonic nanocavity is studied in the third chapter. Our results lead to the concept of optofluidic near-field optical microscopy. In the fourth chapter, we study the dynamics and the manipulation of trapped microbeads clusters in fluidic flows. The last chapter focuses on the trapping and the manipulation of microbeads at the surface of waveguides using copropagating modes

Testo completoOn chips optical nanocavities have become useful tools for trapping and manipulation of colloidal objects. In this thesis we study the nanocavities as building blocks for optical forces, trapping and handling of particles. Proof of concept of trapping dielectric microspheres appears as the starting point of the development of lab on chip. In the first chapter we go through the literature of optical forces in free space and integrated optics. The second chapter presents the experimental tools for the characterization of nanocavities and the set-up developed to perform optical measurements with the colloidal particles. The third chapter describes the proof-of-concept trapping of polystyrene particles of 500 nm, 1 and 2 µm. In the following chapter we analyze the particle trapping as function of the injected power into the cavities. The chapter five gives some examples of the possibilities of particles handling functions with coupled cavities. Eventually, in the last chapter we show assemblies of particles on different geometry of cavities studied in this thesis
