All-fiber multireflector spectral filters which have potential application in optical communications have been investigated experimentally. These multireflector etalons were produced by aligning equal-length fiber sections with TiO2/SiO2 dielectric mirrors deposited on the end in a silicon v-groove. Fiber sections 1.33mm in length were produced by polishing, with the fibers held in a silicon wafer polishing jig. The fibers were aligned inside the polishing jig using a precision micro positioner. Then four polishing steps with increasingly finer grit were applied to produce high-quality polished end surfaces on each fiber section. Finally, a dielectric mirror was deposited on one end of each fiber section by magnetron sputtering. After characterizing the optical loss, length, and mirror reflectance for each of the fiber sections, sections which were well-matched in length were chosen for assembly of the four-mirror etalon, which had nominal reflectance values of 10%, 50%, 50%, and 10% for the dielectric mirrors. Measured transmittance spectra for a mutireflector spectral filter were compared with calculated spectra. Thermal tuning of the multireflector etalon was also investigated. A 0.34 nm wavelength shift was observed for a 23 [degree] C temperature change, in agreement with prediction.

Recently another book on insect physiology was published. It was restricted to a few focal points as are many of these new insect physiology books, but there was considerable depth in its specialized point of view. We were dis cussing the structure of this book and of insect physiology books, in general, when Prof. Remmert asked me " . . . and what about books on spider physio logy?" Silence. Then I started to explain "oh yes, there is a congress pro ceedings volume on this topic and there is a group with excellent publica tions on another topic . . . ", but I felt that this answer was weak. One can no longer buy the proceedings volume in a bookshop and to read a series of publications on a given topic one must search in a library for a dozen journals. Why is there not a single book on spider physiology comparable with the many books on insect physiology? Are spiders a scientific ivory tower, far from public interest and commercial importance? I do not think so, although spiders are one of the many "forgotten" animal groups which always grew in the shadow of the insects. There are research groups working on spider physiology, there are fascinating phenomena in this animal group and there are plenty of exciting results. Spiders may have been always underresearch ed, but research is progressing. In the last few years, new books have been published, e. g.

Mass Spectrometry is an ideal textbook for students and professionals as well as newcomers to the field. Starting from the very first principles of gas-phase ion chemistry and isotopic properties, the textbook takes the reader through the design of mass analyzers and ionization methods all the way to mass spectral interpretation and coupling techniques. Step-by-step, the reader learns how mass spectrometry works and what it can do. The book comprises a balanced mixture of practice-oriented information and theoretical background. It features a clear layout and a wealth of high-quality figures. Exercises and solutions are located on the Springer Global Web.

With this self-contained and comprehensive text, students will gain a detailed understanding of the fundamental concepts and major principles of photonics. Assuming only a basic background in optics, readers are guided through key topics such as the nature of optical fields, the properties of optical materials, and the principles of major photonic functions regarding the generation, propagation, coupling, interference, amplification, modulation, and detection of optical waves or signals. Numerous examples and problems are provided throughout to enhance understanding, and a solutions manual containing detailed solutions and explanations is available online for instructors. This is the ideal resource for electrical engineering and physics undergraduates taking introductory, single-semester or single-quarter courses in photonics, providing them with the knowledge and skills needed to progress to more advanced courses on photonic devices, systems and applications.
