In the last decade, there has been a rapid growth in research on the wavelength-scale design of materials to control optical information. Photonic crystal microcavities allow the trapping of optical fields in near fundamentally-small volumes, with many diverse applications such as filtering and switching. To effect conditional operations in a microcavity-based device, the nonlinear optical properties of multi-mode microcavities must be explored, and this theme forms the focus of this book. A resonant scattering technique is developed to simultaneously excite multiple microcavity modes with a short-pulse laser. An ultrafast pump-probe experiment is then described which demonstrates all-optical switching and frequency conversion in a silicon microcavity. Using this method, the second-order nonlinear properties of InP-based microcavities are investigated, revealing sum-frequency mixing between two modes. This book should be a significant resource for experimentalists in the nanophotonics community, as it contains comprehensive chapters discussing each of the techniques of sample nanofabrication, numerical modeling, and optical spectroscopy that are instrumental to this work.

|Nonlinear System Identification. A Wavelet based State Dependent Parameter Modeling Approach Книга по Требованию Nguyen-Vu T. |
In this approach, the system' s nonlinearities are analyzed and effectively represented by a SDP model structure in the form of wavelets. This provides a computationally efficient tool to open up the `black-box' , offering valuable insights into the system' s dynamics. Here, 1- dimensional (1-D) approach is first developed based on a conventional SDP model structure which relies on a single state variable dependency. It is then extended into a multi-dimensional approach in order to solve the identification problem of systems with significant multi-variable dependence nonlinear dynamics. The research as well investigates the aspects of noise, stability and other engineering application of the proposed approaches, including: nonlinear identification in the presence of noise, BIBO stability analysis and application studies where the developed approaches have been used in various engineering applications. The work documented in this book presents a new, efficient and systematic approach to the identification of nonlinear dynamic systems using Wavelet based State Dependent Parameter (SDP) models, from structure determination to parameter estimation.
