TL;DR: In this article, the authors report on their activities in design, fabrication, characterization and system integration of refractive microlens arrays for sensors and microsystems, including neural networks and multiple pupil imaging systems for photolithography.
Abstract: We report on our activities in design, fabrication, characterization and system integration of refractive microlens arrays for sensors and microsystems. Examples for chemical analysis systems (, blood gas sensor), neural networks and multiple pupil imaging systems for photolithography (microlens and smart mask lithography) are presented.

TL;DR: In this article, a simple diffusion model was proposed to account for the essential dynamic features of surface-relief grating formation, accounting for intensity and polarization dependences, and it opened new perspectives associated with optically controlled anisotropic diffusion.
Abstract: Large-amplitude negative holographic surface-relief gratings are optically induced by resonant visible exposure in azobenzene dye-containing polymers. We propose a simple diffusion model accounting for the essential dynamic features of surface-relief grating formation. It accounts for intensity and polarization dependences. Understanding of the process appears to be essential for holographic grating applications. It opens new perspectives associated with optically controlled anisotropic diffusion.

TL;DR: In this article, the old film mode matching or transverse resonance method for calculating mode fields in dielectric waveguides is given a new formulation that makes it an efficient, accurate, and general numerical method, ready to exploit standard computer libraries for numerical linear algebra.
Abstract: The old film mode matching or transverse resonance method for calculating mode fields in dielectric waveguides is given a new formulation that makes it an efficient, accurate, and general numerical method, ready to exploit standard computer libraries for numerical linear algebra. Both the scalar and the vector field cases are treated for a rather general class of waveguide cross sections, where the method (like the method of lines) is more accurate and more efficient than sophisticated finite-element and finite-difference methods.

TL;DR: In this paper, a new fiber optic sensor for the detection of refractive index variations is presented based on the generation of surface plasma waves at the interface between a thin metallic layer deposited on the fibre core and a surrounding dielectric medium.
Abstract: A new fibre optic sensor for the detection of refractive index variations is presented. The principle of the sensor is based on the generation of surface plasma waves at the interface between a thin metallic layer deposited on the fibre core and a surrounding dielectric medium. Specific injection of monochromatic light into the fibre allows the detection of a refractive index variation as low as for dielectric media lying in the 1.33 - 1.40 refractive index range. Modelling of sensing signal and experiments are performed. Potential applications are aqueous solution analyses and detection of gases and solvents with a specific polymeric layer.

TL;DR: In this article, a beam coherence-polarization matrix is proposed for describing the properties of a quasi-monochromatic, beam-like field that is both partially polarized and partially coherent from the spatial viewpoint.
Abstract: We present an approach for describing the properties of a quasi-monochromatic, beam-like field that is both partially polarized and partially coherent from the spatial standpoint It is based on the use of a single matrix, called the beam coherence-polarization matrix, whose elements have the form of mutual intensities This approach, which can be viewed as an approximate form of Wolf's general tensorial theory of coherence, appears to be very simple, yet it is able to cover significant aspects of the beam behaviour that would not be accounted for by a scalar theory or by a local polarization matrix approach A peculiar interference law applying to mutual intensities is derived We show through simple examples how this approach leads to distinguish fields that would appear identical in a scalar treatment or in a local polarization matrix description Hints for extensions are given
