The purpose of this new book is to show the main techniques and strategies needed to
design and model simple and complex photonic devices, which can be used for
telecommunications, signar processing or sensing applications. In fact, the modeling
approaches and techniques of photonic devices are not yet well standardized. In many fields,
in particular Silicon Photonics or Polymer Photonics, a few experimental devices have been
presented in literature, but their fundamental modeling and design aspects are still completely
or partially ignored. The high-quality research and review chapters are written by the
members of the Photonics Research Group.
Chapter 1 - In this chapter, an overview of guided-wave optical signal processors for
optical signal processing, space applications and telecommunications systems is presented. In
particular, some aspects of mathematical modeling of these devices are reviewed. Moreover,
many significant examples of photonic sensors for detection of electric fields, angular
velocities, biochemical substances are briefly presented, by putting into evidence the relevant
modeling and design techniques. Finally, an approach to evaluate the sensitivity of rib
waveguides is presented.
