Sommario/riassunto

Linking "standard" but often mutually incompatible analytical techniques - so called hyphenation - generally leads to enhanced analytical performance, so hyphenated techniques are widely used in areas where samples are presented in complex matrices, eg environmental, pharmaceutical and biochemical analysis. With these hyphenated techniques, sample preparation is often the most time-consuming step in analysis, particularly where compounds are present



in low concentration, and it has a huge influence on the quality of the analytical results. Sample preparation is still not given the importance i

Sommario/riassunto

This book highlights the guiding mechanisms as well as the most current and important results in the field of innovative, bio-inspired Bragg fibers. While conventional optical fibers (COF) have several advantages over traditional waveguides, they also suffer from a number of disadvantages which are not present in Bragg fibers due to their minimal nonlinearities, lack of polarization or birefringence effect, lack of Fresnel reflections at the open fiber end, and absence of material or cladding losses. A natural platform for biological and chemical sensing, and with potential to boost communication systems' speed and bandwidth, the primary goal of this book is to apprise readers in academia and industry of properties of EM wave propagation in Bragg fibers with a defect layer. Their major applications in bio/chemical sensing, fuel adulteration sensing, high-temperature sensing, optical dual-channel inline filtering, optical de-multiplexers, optical couplers, and nonlinear soliton generation are presented in detail, along with comparisons of Bragg fibers with alternative structures and their relative pros and cons.
