| The Laboratory for Photonics and Nanostructures, was created in January 2001 and is located in Marcoussis-France. It results from the merging of the Laboratory of Microelectronics and Microstructures (L2M-CNRS) with the Laboratory Concepts and Devices for Photonics, the fundamental division of former France-Telecom/CNET in Bagneux. This new laboratory has inherited both expertise on III-V compounds in microstructures and nonlinear optics. In particular, LPN dwells MOVPE and MBE growth groups with internationally recognised state-of-the-art performance. LPN teams have also developed a large spectrum of studies and experience in Nonlinear optics in III-V microcavities, among which ultrafast dynamics, optical bistability, parametric effects and Raman spectroscopy. These activities are complemented and supported by a high level of technological equipment and clean room facilities. LPN has preserved from its historical roots the concern of addressing the fundamental concepts of physics and nonlinear optics and directing them towards possible applications in information technologies. The growth groups and the nonlinear optics team have been working in close collaboration for almost fifteen years, leading to important results among which those of concern with this project cover the first demonstration of optical bistability in microcavities in 1988 and the first observation of optical patterns in 1999. More recently, the group widened the scope of structures and materials considered. He turned towards optically-pumped active structures and succeeded in realizing large area VCSELs and observing patterns formation therein. Also, new QD material are being developed for realizing structures hosting focusing Kerr optical nonlinearities and operating in a passive (non amplifying) regime. In parallel, studies on the processing capabilities of cavity solitons are undertaken in test systems, such as LCLVs, in order to experiment and validate architectures and configurations for the implementation of optical information plasticity and reconfiguration. | ||
