Optical communication refers to any type of communication that uses light to carry information. An optical communication system is composed of three major components, which include a transmitter, channel and receiver. Transmitter is used to encode a message into an optical signal. Semiconductor devices such as light-emitting diodes (LEDs) and laser diodes are the most commonly used transmitters. The function of a channel is to carry the signal to its destination. Receiver is a component that reproduces the message from the received optical signal. Modern communication relies on optical networking systems which use optical fiber, optical amplifiers, lasers, switches, and routers. The most common type of channel used for optical communications is the optical fiber. The light in an optical fiber is guided by the principle of total internal reflection. The main advantages of optical communication include high bandwidth, exceptionally low loss, large transmission range, and no electromagnetic interference. This book includes some of the vital pieces of work being conducted across the world on various topics related to optical communications. It will serve as a valuable source of reference for graduate and postgraduate students.

Optical fibre is used as a medium to transmit the light signals from one place to another. Optical fibre communication is a communication method wherein the signal is transmitted in the form of light. The fibre wires are preferred over the copper wires for transmitting signals because they offer numerous advantages over electrical cables. Fibre wires have a large transmission capacity and incur only small losses. Additionally, they are also low cost, lightweight, and free from interference. Some major components of optical fibre communications are photo detecting receivers, light signal transmitters, regenerators, optical amplifiers, and beam splitters. Optical fibres have several applications in different fields. However, they are specifically used in the telecommunications industry for internet communication, television signal transmission, and cable television signal transmission. Optical fibres are also used in CCTV surveillance cameras, hospitals, and traffic management systems. This book includes some of the vital pieces of works being conducted across the world, on various topics related to optical fibre communications. It will provide comprehensive knowledge to the readers.

This book focuses on polarization microscopy, a powerful optical tool used to study anisotropic properties in biomolecules, and its enormous potential to improve diagnostic tools for various biomedical research. The interaction of polarized light with normal and abnormal regions of tissue reveals structural information associated with its pathological condition. Diagnosis using conventional microscopy can be time-consuming, as pathologists require an hour to freeze and stain tissue slices from suspected patients. In comparison, polarization microscopy more quickly distinguishes abnormal tissue and provides better microstructural information of samples, even in the absence of staining. This book provides a basic understanding of the properties of polarized light, a description of the polarization microscope, and a mathematical formalism of Mueller matrix polarimetry. The authors discuss various advanced linear and nonlinear optical techniques such as optical coherence tomography (OCT), reflectance and transmission spectroscopy, fluorescence, multiphoton excitation, second harmonic generation, Raman microscopy, and more. They explore the exciting potential of integrating polarimetry with these techniques for possible applications in different areas of biomedical research, as well as the associated challenges. Including the most recent developments on the topic, this book serves as a modern guide to polarization microscopy and advancements in its use in biomedical research.
