Luca Dal Negro - Böcker

This book offers a clear and interdisciplinary introduction to the structural and scattering properties of complex photonic media, focusing on deterministic aperiodic structures and their conceptual roots in geometry and number theory. It integrates important results and recent developments into a coherent and physically consistent story, balanced between mathematical designs, scattering and optical theories, and engineering device applications. The book includes discussions of emerging device applications in metamaterials and nano-optics technology. Both academia and industry will find the book of interest as it develops the underlying physical and mathematical background in partnership with engineering applications, providing a perspective on both fundamental optical sciences and photonic device technology. Emphasizing the comprehension of physical concepts and their engineering implications over the more formal developments, this is an essential introduction to the stimulating and fast-growing field of aperiodic optics and complex photonics.

The development of advanced optical structures has enabled tremendous control over the propagation and manipulation of light waves. At the forefront of these advances is the development of micro- and nanostructured optical devices that have dimensions smaller than the wavelength of light. In particular, the engineering of light localization, optical dispersion and plasmonic fields in complex optical media has the potential to boost the scaling of optical technologies below the diffraction limit, opening unprecedented opportunities for basic and applied research. This book bridges three closely related research fields of nanoplasmonics, metamaterials and light localization in complex media. The goal is to share recent progress, identify critical problems and provide promising solutions for the next generation of photonic functionality. Topics include: metamaterials and superlenses; metamaterials; and optical nanoantennas and decay engineering.

Silicon, the leading material in microelectronics during the decades of the 20th century, also promises to be the key material in the future. Despite many claims that silicon technology has reached fundamental limits, the performance of silicon microelectronics continues to improve steadily. The same holds for almost all the applications for which Si was considered to be unsuitable. The main exception to this positive trend is the silicon laser, which has not been demonstrated. The main reason for this comes from a fundamental limitation related to the indirect nature of the Si band-gap. Many different approaches have been taken to achieve this goal: dislocated silicon, extremely pure silicon, silicon nanocrystals, porous silicon, Er doped Si-Ge, SiGe alloys and multiquantum wells, SiGe quantum dots, SiGe quantum cascade structures, shallow impurity centers in silicon and Er doped silicon. All of these are illustrated in this text.
