Laser heterodyning is now a widespread optical technique, based on interference of two waves with slightly different frequencies within the sensitive area of a photo-detector. Its unique feature - preserving phase information about optical wave in the electrical signal of the photo-detector - finds numerous applications in various domains of applied optics and optoelectronics: in spectroscopy, polarimetry, radiometry, laser radars and lidars, microscopy and other areas. The reader may be surprised by the variety of disciplines that this book covers and satisfied by detailed explanation of...

Due to the development of microscale fabrication methods, microlenses are being used more and more in many unique applications, such as artificial implementations of compound eyes, optical communications, and labs-on-chips. Liquid microlenses, in particular, represent an important and growing research area yet there are no books devoted to this topic that summarize the research to date. Rectifying this deficiency, Microlenses: Properties, Fabrication and Liquid Lenses examines the recent progress in the emerging field of liquid-based microlenses.

Over the past decade biophotonics has appeared as a new department within the academic structure across the globe. With experimental work going back for more than a century, application of the scientific method has shown the importance of biophotonics within biological and medical practice. At the same time, a new mathematical description of physics and biophysics has emerged. Self-Field Theory (SFT) describes the role of photon as a binding agent between an electron and a proton within atomic structures. SFT is being rapidly accepted by the physics community as a distinct physical theory....

This book covers the basics of band structure of silicon and germanium and their influence on photonic properties and discusses system layout and key device components with the application background in mind. Special focus is given to SOI-based interconnects and passive waveguide devices and to germanium-on-silicon heterostructure devices for light detection, modulation, and emission. The high index contrast of SOI shows great promise for submicron waveguide structures suited to integration on chip scale. The Ge/Si heterostructures have already proved the expansion of the spectral range,...

In this book, the author provides a comprehensive coverage of modern numerical modelling techniques for designing photonic devices for use in modern optical telecommunications systems. In addition the book presents the state-of-the-art in computational photonics techniques, covering methods such as full-vectorial finite-element beam propagation, bidirectional beam propagation, complex-envelope alternative direction implicit finite difference time domain, multiresolution time domain,...
