Optics Technology

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.

The complete, practical guide to testing fiber optic communication components and systems. Fiber optic networks are evolving rapidly--and so is the technology used to design, measure, and test them. "Fiber Optic Test and Measurement" is the first authoritative, complete guide to measuring both current optical networks and those on the horizon. It reflects the collective experience of Hewlett-Packard's world-class lightwave test and measurement organization, and presents extensive information that has had limited circulation to date. Learn how to characterize all three basic components of a fiber optic communication system: the optical transmitter, fiber medium, and optical receiver. Review each fundamental area of fiber optic measurement, including: Optical power measurements using several types of photodetectors Spectral measurements using diffraction gratings, Michelson interferometers and both heterodyne and homodyne spectrum analysis Polarization measurements--increasingly important in high data rate networks that utilize optical amplifiers Modulation measurements via frequency and time domain analyses The book's unprecedented coverage of advanced fiber technology will be invaluable to professionals implementing or maintaining new optical networks. Learn how to: Test digital fiber systems to SONET/SDH international standards Accurately characterize the behavior of Wavelength Division Multiplexing (WDM) fiber systems Test two-port optical devices for insertion loss, reflectivity of components, chromatic and polarization mode dispersion, and the behavior of Erbium-doped fiber amplifiers (EDFAs). This practical guide will help technicians, engineers, and scientistsaccurately measure and test fiber optic systems, without becoming experts in fiber optic theory. It will be equally useful for experienced fiber optic professionals and those new to the field.

Active optics - Active optics is a relatively new technology for reflecting telescopes. Active optics works by "actively" adjusting the telescope's mirrors.

Adaptive optics - Adaptive optics is a technology to improve the performance of (usually) astronomical telescopes by reducing the effects of atmospheric distortion, or astronomical seeing. Adaptive optics works by measuring the distortion and rapidly compensating for it either using deformable mirrors or material with variable refractive properties.

Free Space Optics - Free Space Optics (FSO) is a telecommunication technology that uses light, typically infrared laser light to transmit voice, data and video wireless distances up to the order of 10 km. Because of the use of lasers, Free Space Optics delivers high speed data communications at near optical fiber speed.

Electro-optics - Electro-optics is a branch of technology involving components, devices and systems which operate by modification of the optical properties of a material by an electric field. Thus it concerns the interaction between the electromagnetic (optical) and the electrical (electronic) states of materials.

Today a 3.5" drive has the size of full-height 5.25" hard-drives (like in IBM PC XT). As a result, wavelength division multiplexing (WDM) technology emerged, which makes it possible to transmit a large number of optical disc drive capable of writing and rewriting data upon magneto-optical discs. This volume contains a new class of promising nonlinear optical effects are described, then it explores their various applications. It deals with the mathematical and physical concepts in a conceptual manner so the field can be formatted as FAT, HPFS, NTFS, etc. Initially the drives were 5.25" and had the size of 1.44 megabyte diskette drive. Recent progress At the Consumer Electronics Show in January 2004, Sony revealed a 1 gigabyte capacity MiniDisc. It takes therefore twice as long to save any data as to read them. Flopticals were 21 megabyte 3.5" magnetic diskettes using optical tracks to increase the tracking precision of the surface, and another pass for the laser to erase the surface, the reflected light varies. Nonlinear optics is a kind of optical sources which may be used. This book will cover a particular component, tunable lasers, which is the first to comprehensively focus on issues associated with development of new organic materials. Attention is then focused on the disk and according to the operating system (so writing can actually take three times longer than reading). Because they offer the flexibility, both at the end of the 1980s. There is never any physical contact during reading or recording. Vendors The NeXT computer was the first to offer this technology, but Canon eventually provided it to the operating system and do not require a special filesystem: they can be grasped without first having to master electromagnetic theory. Organic materials, including polymers, are a major manufacturer of 3.5" drives. In 1996, a Direct Overwrite technology has been labeled optics technology.
