Semiconductor optical amplifiers
IEEE Circuits and Devices Magazine, 1989An overview of semiconductor optical amplifier characteristics and their potential applications is presented. The latter consist of nonregenerative repeaters, optical receiver preamplifiers, power amplifiers and amplifier/modulators, general optical gain blocks, narrowband tunable amplifiers, and bistable amplifiers. >

Packaging Of Semiconductor Optical Amplifiers
SPIE Proceedings, 1990Semiconductor optical amplifier packaging is described using a localized cooling soldering approach for attaching and aligning two separate single mode fibers. The alignment process is more critical for amplifiers than for lasers because fiber coupling loss directly reduces any gain achieved by the semiconductor.

Progress in Semiconductor Optical Amplifiers
Optical Amplifiers and Their Applications, 1990Optical amplifiers are the fundamental building blocks required for the development of future all-optical networks. The elimination of electronic bottlenecks will allow the development of new network architectures which, for example, will enable the realisation of a network that has the flexibility to meet rapid changes in demand for capacity.

Linear Semiconductor Optical Amplifiers
2012The chapter reviews properties and applications of linear semiconductor optical amplifiers (SOA). Section 12.1 covers SOA basics, including working principles, material systems, structures and their growth. Booster or inline amplifiers as well as low-noise preamplifiers are classified. Section 12.2 discusses the influence of parameters like gain, noise

Applications of semiconductor optical amplifiers
2012 17th Opto-Electronics and Communications Conference, 2012All-optical processing of phase encoded signals with nonlinear semiconductor optical amplifiers offers potential advantages. As examples, we demonstrate QPSK to 8PSK conversion and decomposition of QPSK to two BPSK outputs at new wavelengths.

Semiconductor Optical Amplifiers for FTTx
2007 9th International Conference on Transparent Optical Networks, 2007Access networking is a hot topic. After Japan and Korea, demand is now picking up also in Europe and the US. After cherry-picking the easy installs, operators find that they could use a power boost in their passive optical networks to reach further out neighbourhoods from their present set of PON central offices.

Optical bistability in vertical-cavity semiconductor optical amplifiers
Applied Optics, 2006We present an overview of the properties and applications of optical bistability in vertical-cavity semiconductor optical amplifiers (VCSOAs). The basic physics and analytical models of this optical nonlinearity are discussed. Experimental results obtained from a VCSOA operated in the 850 nm wavelength region are presented.

Applications of semiconductor optical amplifiers
24th European Conference on Optical Communication. ECOC '98 (IEEE Cat. No.98TH8398), 2002An overview is given of applications of semiconductor optical amplifiers in optical communication systems. Feasibility is demonstrated for optical pre-amplifier and in-line applications. Experiments on WDM transmission are presented as well as the use of gain-clamping to achieve linear or analog-grade amplification.

Current commercial applications of semiconductor optical amplifiers
2014 16th International Conference on Transparent Optical Networks (ICTON), 2014SOAs seem to have finally found their niche. We will review the applications in which semiconductor optical amplifiers are presently used, and will go into the characteristics that make the devices distinctively suited for these purposes. We notice that the modern uses of SOAs are not limited to optical networking, but can also be found in fields as ...
