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. >

Theory of optical amplifier chains
Journal of Lightwave Technology, 1998An analytical theory of the dynamical behavior of erbium-doped amplifier (EDFA) chains is developed. A simple and detailed physical picture is presented, explaining the speeding up and the appearance of overshoots in the transient response. The speed of the transients is shown to be proportional to the number of the amplifiers in the chain.

Television-optical operational amplifier
Applied Optics, 1979The advantages of negative feedback are well known in electronics and extensively used in the operational amplifier. The properties of such a system are nearly independent of the parameters in the forward branch of the system; they are only determined by external elements in the backward branch.

Introduction When an electromagnetic wave propagates through amedium stimulated emissions increase the intensity of the wave, while absorptions diminish it. The overall intensity will increase if the number of stimulated emissions can be made larger than the number of absorptions. If we can create such a situation then we have built an amplifier that

Multipass optical parametric amplifier
Optics Letters, 1996A compact, low-threshold, multipass optical parametric amplifier has been developed for the conversion of short-pulse (360-ps) 1064-nm Nd:YAG laser radiation into eye-safe 1572-nm radiation for laser ranging and radar applications. The amplifier had a threshold pump power of as low as 45 microJ, and at three to four times this threshold pump power the ...

The two main attractions of optical amplifiers in fibre telecommunications lie in the possibility of eliminating the complex electronic regenerators currently in use in submerged systems and the provision of a large optical fan-out in networked systems. These two applications are shown illustratively in fig(1).
