This book was released on 2015-11-10 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon photonics technology, which has the DNA of silicon electronics technology, promises to provide a compact photonic integration platform with high integration density, mass-producibility, and excellent cost performance. This technology has been used to develop and to integrate various photonic functions on silicon substrate. Moreover, photonics-electronics convergence based on silicon substrate is now being pursued. Thanks to these features, silicon photonics will have the potential to be a superior technology used in the construction of energy-efficient cost-effective apparatuses for various applications, such as communications, information processing, and sensing. Considering the material characteristics of silicon and difficulties in microfabrication technology, however, silicon by itself is not necessarily an ideal material. For example, silicon is not suitable for light emitting devices because it is an indirect transition material. The resolution and dynamic range of silicon-based interference devices, such as wavelength filters, are significantly limited by fabrication errors in microfabrication processes. For further performance improvement, therefore, various assisting materials, such as indium-phosphide, silicon-nitride, germanium-tin, are now being imported into silicon photonics by using various heterogeneous integration technologies, such as low-temperature film deposition and wafer/die bonding. These assisting materials and heterogeneous integration technologies would also expand the application field of silicon photonics technology. Fortunately, silicon photonics technology has superior flexibility and robustness for heterogeneous integration. Moreover, along with photonic functions, silicon photonics technology has an ability of integration of electronic functions. In other words, we are on the verge of obtaining an ultimate technology that can integrate all photonic and electronic functions on a single Si chip. This e-Book aims at covering recent developments of the silicon photonic platform and novel functionalities with heterogeneous material integrations on this platform.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of two-dimensional (2D) materials brings up new opportunities for 2D physics and new applications. Among them, semiconductor transition metal dichalcogenides (TMDCs) show quite advanced properties. Especially, in the monolayer limit they become direct-bandgap semiconductors. The monolayer form demonstrates a range of optical effects including photoluminescence (PL), valley polarization and second-harmonic generation (SHG), which are important for future optoelectronic applications. However, the light-emitting efficiency of such monolayer TMDCs is generally low due to the subnanometer light-matter interaction length and defects. To enable their practical applications, new schemes are desirable to enhance the emission efficiency and further control properties such as directionality and polarization. On the other hand, photonic nanostructures show great capability to manipulate light-matter interaction at the nanoscale. Thus, in this thesis, we explore different schemes to enhance and control emission from monolayer TMDCs by integrating them with resonant photonic nanostructures, including plasmonic structures, waveguides and nanoantennas. We have successfully demonstrated integration of monolayer TMDCs into different photonic platforms experimentally and showed great capability to control the emission from them. Associated theoretical work has also been presented. Our work shows potential important applications for future optoelectronic devices. In Chapter 1, we firstly introduce the necessary background of the development of 2D materials and semiconductor optics. Then, we focus on the optoelectronic properties of 2D TMDCs. The prospect of integration of 2D materials with photonic nanostructures is further discussed. In Chapter 2, we show integration of a monolayer MoSe2 onto resonant plasmonic nanoantenna. Comprehensive control of the PL emission from quenching to enhancement is demonstrated by changing the thickness of the spacer between the MoSe2 and nanoantenna. Further simulation results explain the experimental observation well. In Chapter 3, we demonstrate enhanced and directional PL emission from WSe2 monolayer integrated onto a silicon photonics structure. This is achieved by coupling the WSe2 into a multi-resonant grating-waveguide structure which supports several leaky waveguide modes. Further theoretical work explains our experimental results well. In Chapter 4, we propose a plasmonic-TMDCs scheme that could effectively separate the PL emission from different valleys of 2D TMDCs into opposite directions spatially. This is realized by simultaneously exciting both electric dipole and quadrupole modes from two-bar plasmonic antenna, the interference of radiation of these modes induces the spin-locked directionality. In Chapter 5, we demonstrate enhanced SHG from a monolayer MoSe2. This is achieved by integrating the monolayer onto a waveguide and exciting the material through evanescent field of the guided modes. The enhancement is due to the fact that the waveguide geometry dramatically increases the nonlinear interaction length and allows for phase matching. Theoretical calculation further reveals the conversion mechanism in our system and points out further directions. In Chapter 6, we summarize the work and discuss the future prospects in regards to the integration of 2D materials with resonant photonic nanostructures.

This book was released on 2016-05-01 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The considerable proliferation of new glasses during the second half of the 20th century (germanate, vanadate, bismuthate, tellurite, chalchogenide glasses, etc.) brought about the use the plural form of the 4 generic glass denomination, in order to be able to index each emerging glass family by its proper name, as well as to classify them methodically. Together with its great compositional versatility, the peculiar characteristics of glass (non-crystalline structure with short-range order, continuous network with no intergranular boundaries, isotropy, easy to be formed into a plastic state inside a wide temperature range) allow for a freedom of design and adaptability that few materials are able to offer. All these circumstances have contributed to the fact that, in the last seventy years, glass has acquired the multiple and varied appearance of its new families, without losing neither its original image nor its soda-lime-silica traditional composition, destined for the huge industrial manufacture of its conventional products.
