abstract: Although the field of nonlinear optics is over 25 years old. our understanding of the nonlinear optical properties of solids is poor. For kh(3) simple bonding molecular orbital approaches1 are unable to account in a quantitative way for the magnitude, dispersion or anisotropy. On the other hand, the number of full band structure calculations of the nonlinear optical constants of solids, arid semiconductors in particular, is small. The difficulties associated with these calculations is two fold: first is the complex nature of the nonlinear response function itself, and second is the requirement of knowing both the electron energy bands and wavefunctions through the Brillouin zone. The only previous full band structure calculation of kh(3) focussed solely on the zero frequency limit and did not address its anisotropy which has been known for some time3,4. It has been suggested by some authors1 that the magnitude and anisotropy of kh(3) could only be understood in terms of local field effects.

title: THIRD HARMONIC GENERATION IN CRYSTALLINE AND AMORPHOUS SILICON

abstract: model. A final chapter gives a brief introduction to the problem of ergodicity in the foundation of statistical mechanics. The book contains a beautiful selection of topics presented with the pioneering insights of the authors, and gives concise and clear review of a wide range of ideas. The field is difficult and technical, and so the book will require some effort and patience on the part of the reader. There are also a number of unfortunate typing errors, including errors in some equations. This means that the book may not be suitable as an exclusive first introduction to the topics, and would probably benefit from being read in conjunction with other texts. However, it is rarely the case that a review by pioneers would be anything other than full of insight. This book is no exception. A scientifically mature reader would hence benefit from using it both as an overview of the field, and as a lifelong reference guide to some of its major techniques.

abstract: inclusion of problems, and solutions? perhaps even the smell of the paper/ink? I doubt there is one criterion (though my local book shop groups books by the colour of the cover an interesting approach! My list of favourites just gained a new recruit, Optical Properties of Solids, by Mark Fox. Each of us has I suspect a list of favourite text books. Our choices are in part based on the particular topics covered in a book, but I fancy that much to do with the choice comes down to the approach adopted by the author, especially the extent to which that resonates with our own way of thinking. My initial reading of this book was that it did not follow an approach that I had an immediate empathy for. There are two approaches that often seem to define the discipline of physics: trying to understand why things are the way they are, and identifying how we know the things we know. Whilst these are skills, perhaps even ideologies, that we hope our students may come to adopt, they are not always the best ways of initiating students in new topic areas. It seems to me that Mark Fox understands this point very well. The topic of optical materials could fill volumes, yet he has chosen his material carefully, and has in particular chosen the level of discussion with care too, frequently making simple statements about how things are, e.g. sometimes giving formulae without derivation. Initially I found this rather sweeping approach dissatisfying, but more thought, and especially trying out some of the material on my own students, quickly showed me its value, it is above all accessible. The key to this book is that the connections with the underlying physics are always at the forefront and clearly identified. One example of this is the care taken over the section concerning the physics of oscillators in Chapter 2. This topic underpins so much of how we understand many optical (and other) materials that without such a clear grounding students will not easily gain the physical understanding that they may wish, and certainly need. Fox has appreciated this point, and has also provided exercises to reinforce students' learning in this vital area. In addition to such key fundamentals, the book also contains a number of insights that make a real difference, and are all too often left from many texts. As an example, in his discussion on oscillators, Fox shows how one can understand the fact that a resonance can influence the refractive index of a material over a wider spectral range that the associated absorption. This second edition of the book is also up to date in that it includes many of the new areas that students and others are likely to want to explore, for example plasmonics, carbon nanostructures, sources for single photons (such as NV centres in diamond) and negative refraction. Whilst no introductory text can go into great depth on such topics, the fact that Fox has introduced them, and related their properties to topics covered elsewhere in the book, does make the introduction to these new topics of considerable value. Whilst they will not be enough for someone embarking on research in these areas, they will provide the basis for future study, especially when combined with the well prepared suggestions for further reading. All in all I think this is set to become a standard work. Fox has woven together an informative and practical text, rooted in the underlying physics that will help students build an understanding of the optical properties of everything from glass to graphene.

abstract: We compare the physical and morphological properties of z 2 Lyman alpha emitting galaxies (LAEs) identified in the HETDEX Pilot Survey and narrow band studies with those of z 2 optical emission line galaxies (oELGs) identified via HST WFC3 infrared grism spectroscopy. Both sets of galaxies extend over the same range in stellar mass (7.5 logM 10.5) size (0.5 R 3.0 kpc) and star formation rate ~1 SFR 100) Remarkably, a comparison of the most commonly used physical and morphological parameters stellar mass, half light radius, UV slope, star formation rate, ellipticity, nearest neighbor distance, star formation surface density, specific star formation rate, [O III] luminosity, and [O III] equivalent width reveals no statistically significant differences between the populations. This suggests that the processes and conditions which regulate the escape of Ly alpha from a z 2 star forming galaxy do not depend on these quantities. In particular, the lack of dependence on the UV slope suggests that Ly alpha emission is not being significantly modulated by diffuse dust in the interstellar medium. We develop a simple model of Ly alpha emission that connects LAEs to all high redshift star forming galaxies where the escape of Ly alpha depends on the sightline through the galaxy. Using this model, we find that mean solid angle for Ly alpha escape is 2.4+ 0.8 steradians; this value is consistent with those calculated from other studies.

abstract: In the present work we study the growth by pulsed laser deposition of YBa$_2$Cu$_3$O$_{7 \delta} (YBCO) films on the r cut sapphire substrates. To improve the matching of the lattice parameters between the substrate and the film we use CeO$_{2} buffer layer, recrystallized prior to the deposition of YBCO. The optimal thickness and temperature of recrystallization of the buffer layer is first determined using atomic force microscopy (AFM) and X ray diffraction. Next, we use the AFM to examine the dependence of YBCO film roughness on the film thickness, and we study the homogeneity of magnetic flux penetration into the films by magneto optical imaging. We find that the superconducting critical temperature and critical current density of these films are very similar to those of YBCO films grown on well matched substrates. It appears that the microstructure of YBCO films is affected by structural defects in the buffer layer as well as variations in oxygen deficiency, which results in high values of critical current density suitable for application.

abstract: Despite the recent surge of interest in two dimensional (2D) inorganic nanosheets derived from photoactive coordination polymers of lanthanide ions having interesting optical properties, research in this area is still in its infancy. Luminescent lanthanide ions, Eu(iii) or/and Tb(iii) as well as a bis terpyridine ligand (L) were used in this study as the building blocks for the synthesis of the archetypical layered structure of coordination polymers (CPs) (L*Eu/L*Tb) 2D nanosheets were obtained through exfoliation of the layered precursor of CPs in a suitable solvent system following a sonication assisted strategy. These nanosheets exhibit lateral sizes on the micrometer scale (0.3 1 mm) and an ultrathin thickness of 2 6.5 nm. 1,1 Diamino 2,2 dinitroethene or FOX 7 is an insensitive high explosive; in a binder mixture, it exhibits a slightly superior detonation velocity of 8870 m s 1 in comparison to RDX. The insensitive nature of FOX 7 makes it a key component for the development of low vulnerable high explosive compositions for further application in weaponry. The growing demand for FOX 7, for use as a suitable replacement of conventional explosives, is of serious concern to human security. Achieving rapid and efficient detection of this unexplored explosive is a challenging task. In the present study, the developed luminescent nanosheets were used for the first time for micromolar level detection of FOX 7 both in solution and in the solid state. A visually distinct color change of the nanosheets from red (L*Eu) and green (L*Tb) to colorless was witnessed upon UV light irradiation during the detection process. Notably, the solid state detection technique could be exploited for developing a commercial spray kit for quick onsite screening of this important explosive.

abstract: A comprehensive analysis of guided modes of a novel type of a planar Bragg reflection waveguide which consists of a low refractive index guiding layer sandwiched between two finite aperiodic mirrors is presented. The layers in the mirrors are aperiodically arranged according to the Kolakoski substitution rule. In such a waveguide light is confined inside the core by Bragg reflection from the mirrors, while dispersion characteristics of guided modes strongly depend on aperiodicity of the cladding. Using the transfer matrix formalism bandgap conditions, dispersion characteristics and mode profiles of the guided modes of such Bragg reflection waveguide are studied.

abstract: The study of crystal optics is largely a matter of solid geometry, and demands clear visualization of optical properties in their three dimensional relations. To aid students in visualizing these relations, numerous models of wood, wire, glass, and plaster have been devised,l and have proven to be of definite value. The models described in this paper were designed, in part to supplement, and in part to substitute for standard types already in use. Following the precedent of Wright' and Rogers,t emphasis is placed on the indicatrix, or index ellipsoid, and its relations to crystallographic directions and to common optical phenomena. Relations heretofore shown only by tqo dimensional drawings, by solid opaque models, or by elusive wire "bird cages" are clearly represented in three dimensions by transparent models made of sheet celluloid. The models described below were constructed for the Petrographic Laboratory of the University of Kansas by student workers as a project under the National Youth Administration. Particular credit is due to Mr. Hugh Magruder and to Mr. Raymond Leonard for skilled workmanship and for ingenuity in working out details of construction. Photographs of the models were made by Mr' Oren Bingham, director of the University Photographic Bureau.
