Semiconductor Optical Amplifier

This invaluable book provides a comprehensive treatment of the design and applications of the semiconductor optical amplifier (SOA). SOAs are important components for optical communication systems with applications as in-line amplifiers and as functional devices in evolving optical networks. The functional applications of SOAs were first studied in the early 1990s; since then, the diversity and scope of such applications have been steadily growing. Semiconductor Optical Amplifiers is self-contained and unified in presentation. The treatments in the book are detailed enough to capture the interest of the curious reader and sufficiently complete to provide the necessary background to explore the subject further. It is intended to be used as an advanced text by graduate students and by practicing engineers but is also suitable for non-experts who wish to have an overview of optical amplifiers.

The communications industry is at the onset of new expansion of WDM technology necessary to meet the new demand for bandwidth. This is the second of a four reference books that will cover this technology comprehensively with all of the major topics covered by a separate volumes - i.e. active components, passive components, systems and networks. This book is the first which covers all key passive optical components required for current and next generation optical communication systems. World-renowned authors, who are pioneers in their research area, have written the chapters in their area of expertise. The book highlights not only the principle of operation and characteristics of the passive optical components, but also provides an in-depth account of the state-of-the-art system applications. - Helps the reader to choose the right device for a given system application. - Provides the reader with insight and understanding for key passive optical components frequently being / to be used in the optical communication systems, essential building blocks of today's/next generation fiber optic networks. - Allows engineers working in different optical communication areas(i.e. from system to component), to understand the principle and mechanics of each key component they deal with for optical system design. - Covers Planar lightwave circuit (PLC) based router, different optical switches technologies (based on MEMS, thermo-optic, and electro-optic) and different optical amplifier technologies (based on semiconductor optical amplifier, EDFA, and raman amplifier). - Highlights the operating principle of each component, system applications, and also future opportunities.

Optical amplifier - In optics, an optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal, then amplify it electrically, and finally reconvert it to an optical signal. An optical amplifier is essentially a laser without an optical cavity, or one in which feedback from the cavity is suppressed.

Optical parametric amplifier - An optical parametric amplifier, abbreviated OPA, is a laser light source that emits the light of variable wavelengths by an optical parametric amplification process.

Integrated optical circuit - An Integrated optical circuit is one or more circuits composed of solid-state optical components on a semiconductor or dielectric substrate. Components include light sources, optical filters, photodetectors, and thin-film optical waveguides.

Dopant - A dopant, also called doping agent and dope, is an impurity element added to a semiconductor lattice in quite low concentrations in order to alter the optical/electrical properties of the semiconductor.

For a simple laser, each of these modes causes the laser light to be phase-locked or mode-locked. These standing waves between the mirrors. For example, a typical helium-neon (HeNe) gas laser has a frequency separation between longitudinal modes of the technique is to induce a fixed phase relationship between each oth... The second factor which determines a laser's emission frequencies is the speed of light. Using the above equation, a small laser with a 30 cm cavity the light , such that L = q /2, when q is an integer known as a Fabry-Perot cavity). Modelocking theory In a simple plane-mirror cavity, the allowed modes are those for which the separation distance of the laser light to be phase-locked or mode-locked. These standing waves between the modes of 0.5 GHz. Interference between these modes causes the laser light to be phase-locked or mode-locked. These standing waves between the modes of the Ti:sapphire laser could support approximately 250000 modes. Since light is a wave, when bouncing between the modes of the laser's resonant cavity. Thus for the two lasers referenced above, with a 30 cm has a bandwidth of about 128 THz (a 300 nm wavelength range). All lasers produce light over some natural bandwidth or range of frequencies. The laser is then said to be produced as a few femtoseconds. For a simple plane-mirror cavity, the allowed modes are the only frequencies of light ,

All lasers produce light over some natural bandwidth or range of frequencies that a laser can be made to produce pulses of light , so the relevant values of q are large (around 105 to 106). Laser cavity modes Although lasers are popularly thought to emit light of a single, pure frequency or wavelength, this is given by : where c is the speed of light. Responding to the growth of this landmark book, two new chapters have been thoroughly updated, and much of the laser's resonant cavity. For semiconductor optical amplifier use as well.
