This book was released on 2011-05-18 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book concentrates on the mathematics of photonic crystals, which form an important class of physical structures investigated in nanotechnology. Photonic crystals are materials which are composed of two or more different dielectrics or metals, and which exhibit a spatially periodic structure, typically at the length scale of hundred nanometers. In the mathematical analysis and the numerical simulation of the partial differential equations describing nanostructures, several mathematical difficulties arise, e. g., the appropriate treatment of nonlinearities, simultaneous occurrence of continuous and discrete spectrum, multiple scales in space and time, and the ill-posedness of these problems. This volume collects a series of lectures which introduce into the mathematical background needed for the modeling and simulation of light, in particular in periodic media, and for its applications in optical devices.

Available in PDF, EPUB and Kindle. Book excerpt: This edited volume is devoted to the now-ubiquitous use of computational models across most disciplines of engineering and science, led by a trio of world-renowned researchers in the field. Focused on recent advances of modeling and optimization techniques aimed at handling computationally-expensive engineering problems involving simulation models, this book will be an invaluable resource for specialists (engineers, researchers, graduate students) working in areas as diverse as electrical engineering, mechanical and structural engineering, civil engineering, industrial engineering, hydrodynamics, aerospace engineering, microwave and antenna engineering, ocean science and climate modeling, and the automotive industry, where design processes are heavily based on CPU-heavy computer simulations. Various techniques, such as knowledge-based optimization, adjoint sensitivity techniques, and fast replacement models (to name just a few) are explored in-depth along with an array of the latest techniques to optimize the efficiency of the simulation-driven design process. High-fidelity simulation models allow for accurate evaluations of the devices and systems, which is critical in the design process, especially to avoid costly prototyping stages. Despite this and other advantages, the use of simulation tools in the design process is quite challenging due to associated high computational cost. The steady increase of available computational resources does not always translate into the shortening of the design cycle because of the growing demand for higher accuracy and necessity to simulate larger and more complex systems. For this reason, automated simulation-driven design—while highly desirable—is difficult when using conventional numerical optimization routines which normally require a large number of system simulations, each one already expensive.

This book was released on 2011 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research was undertaken with the aim of establishing a comprehensive simulation platform for the investigation of light propagation in active and passive silicon photonic structures. It is essential to perform detailed numerical simulations to gain a clear insight into the interplay of optical nonlinearities in silicon for improving the performance of silicon based photonicdevices. Such detailed numerical simulations may also lead to novel device concepts and substantially extend the capabilities of silicon photonics in the future. The well-established finite-difference time-domain (FDTD) technique is preferred for such detailed simulations because the FDTD scheme allows electromagnetic field equations to be solvedwithminimal assumptions. Moreover, unlike most other simulation models, the FDTD models are restricted neither by the single-mode assumption nor by the slowly varying envelope approximation.In the first stage of the research, a two-dimensional FDTD simulator that takes into account the linear and nonlinear optical properties of silicon was developed. The dominant linear optical effects included in this FDTD algorithm were material dispersion and linear absorption in silicon, while the dominant nonlinear optical effects included were stimulated Raman scattering, the Kerr effect, two-photon absorption, free-carrier absorption, and free-carrier dispersion.The developed simulator was used to investigate the Raman-mediated nonlinear interaction of co-propagating and counter-propagating pulses inside silicon waveguides. This analysis shows unambiguously that second-order Stokes and anti-Stokes sidebands of sufficiently high intensities can develop from noise when the two pulses are co-propagating, but these sidebands are absent when these pulses counter-propagate, due to an inherent phase mismatch. In addition, the evolution of interacting pulses in the temporal and frequency domains was studied using the developed two-dimensional simulator.In stage two, by incorporating the anisotropy of silicon optical nonlinearities and the vectorial nature of the electromagnetic field, a fully functional three-dimensional FDTD algorithm was developed for the analysis of silicon photonics devices. Modeling of the anisotropy of the Kerr effect, two-photon absorption, and stimulated Raman scattering was undertaken and presented.Under certain realistic conditions that prevent generation of the longitudinal optical field inside the waveguide, thismodel was simplified considerably and was represented by a computationally-efficient algorithm, suitable for numerical analysis of complex polarization effects. Using this FDTD simulator, polarization dependence for several nonlinear effects, including self-phase modulation, cross-phase modulation, and stimulated Raman scattering, was studied. Owing to its generality in handling complex waveguide geometries and short optical pulses, the proposed three-dimensional FDTD algorithm is very useful for testing the suitability of anisotropic nonlinearities for different siliconbased photonic devices.In addition, this research has resulted in the development of several essential post-processing tools for the analysis of FDTD simulation results. These tools include a spectrummonitor for transforming the time domain results into the frequency domain, an energy flow monitor for investigating the propagation of energy within the silicon structures, and a visualization tool for investigating the evolution of electromagnetic wave polarization.

This book was released on 2015 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, the Finite-Element Method (FEM) was utilized to simulate and design the optimal nanostructures for better performances of Surface-Enhanced Raman Scattering (SERS) and lasing. FEM proved its effectiveness in the calculations of target physical models to optimize the model geometry or theoretically validate experimental observations. In chapter 1 and 2, the fundamental theorem of SERS and photonic crystal cavity were introduced and discussed. The most used optical structures for the two effects, metal/dielectric SPP structure and dielectric photonic crystal structure, were introduced as examples. Equations stem from Maxwell equations were derived and discussed to clarify the concepts of SERS and PCC. In chapter 3, the FEM method was carried out to simulate the SERS performance of Au nano-bowl/SiO2/Au nanoparticle structure. The electric field distributions and Raman enhancement factors of models in real experiments were calculated and analyzed theoretically. The simulation result on Raman enhancement factors showed consistency with the experimental observations. In chapter 4, the design process of silicon nitride photonic crystal cavity was introduced and the simulation results were discussed. Using L3 geometrical model, the FEM method successfully revealed the relations between key optical properties, such as quality factor and resonant wavelength, and geometrical parameter selections. The simulations were also helpful in determination of the optimal parameter selection in L3 PCC model for further experimental fabrication.
