J.-E. P. C. Communal,G. Largounez,A. B. Grudinin,M. In Het Panhuis,W. J. Blauern California, I compared plant species richness on 24 small (<5 ha) serpentine outcrops and 24 equally-spaced sites within large (> 1 km<sup>2</sup>) outcrops. For serpentine endemic plants, alpha (local) diversity was lower but beta (differentiation) diversity was higher on small outcrops compare

Non-Linear Optical Technology in Present and Future Transmission Systems and Optical Networksdden. Nevertheless, the photonic technology industry strongly participates to the present expansion especially in the telecommunication domain. The maturing of WDM technologies has provided the key towards success. The requirements for data transmission capabilities related to the development of the

Characterization of AlGaAs/AlAs Waveguides for Optical Parametric Generationform birefringence for phase-matching. We emphasize the role of a careful characterization in achieving parametric fluorescence and oscillation. In particular, we present the results of two complementary optical techniques, providing a more accurate estimate of refractive indices than extrapolated f

All-Optical Diode in a Quasi-Phase-Matched LiNbO3 Waveguideing grating in an Annealed Proton-Exchanged LiNbO. channel waveguide. For input powers beyond 1.5 W we observe the onset of a noticeable non-reciprocal response, in good agreement with predictions, reaching a contrast as high as 90% with an input power of 3.1W.

Feasibility of All-Optical Computation by Second Harmonic Generated Hologramsavefronts that are made interact in a non-linear crystal endowed with second order non-linearity (.-BaB.O.). The sum-frequency interaction reconstructs a holographic image containing the outputs of the desired operations, and difference frequency also demonstrated to be effective. The experiments de
