Modern communication technologies have revolutionized society and econ- omy on a global scale, and progress in this field is still breathtaking. Among the crucial features of these developments is the possibility to transmit/receive ever-increasing bit rates at lower and lower cost. This is due to some ex- tent to improved electronics, but it is much more due to the capabilities of opticaL fibre-based communication systems. Optical communication tech- nologies were initially introduced in order to improve traditional information exchange, but they have recently become a key prerequisite for...

This is the first book dedicated to wavelength filters for fibre optics. It provides a comprehensive account of the principles and applications of such filters, including their technological realizations. It explains the relevant performance parameters, the particular advantages and shortcomings of the various concepts and components, and the preferred applications. There is also in-depth information on the characteristics of commercially available devices.

Information and communication technologies have been growing and - veloping steadily for as long as any of us can remember. Growth was p- ticularly strong in the last few decades, and fibre optic communication s- tems have become predominant whenever information is to be transmitted over medium or long distances. Even when the 'telecommunication bubble' burst at the beginning of the new millennium, the only thing which vanished was the expectation of making a fortune by buying and reselling telecom device and equipment manufacturing companies; the upgrading of existing fibre optic links and...
