Linear optical amplifiers [PDF]
The 15th Annual Meeting of the IEEE Lasers and Electro-Optics Society, 2002 The linear optical amplifier is a single chip InP-based optical amplifier targeting applications in access, metro and DWDM networks. Device and system results of this new class of chip-based amplifiers demonstrate the linear performance.

Abstract This article presents an application of a recently published probablistic model for traveling wave optical amplification. Both optical signal and amplified spontaneous emission (ASE) noise are modeled as bunches of photons traveling along the amplifying region with size varying according to simple random rules. The results of the theory enable

Optical amplifiers for optical networks
1997 Digest of the IEEE/LEOS Summer Topical Meeting: Vertical-Cavity Lasers/Technologies for a Global Information Infrastructure/WDM Components Technology/Advanced Semiconductor Lasers and Applications/Gallium Nitride Materials, Processing, and Devices (C, 2002The erbium doped fiber amplifier (EDFA) is a key enabler of WDM transmission systems and wavelength routed optical networks. EDFAs are well suited to compensate the optical loss of network elements and transmission spans. Although the EDFA's are almost ideal in their characteristics, they are not quite perfect.

The development of low-loss optical silica fibres and reliable semiconductor laser sources in the early 1970s have enabled the practical realisation and massive deployment of optical-fibre communications worldwide. However, high bit-rate transmission is severely limited by the fibre residual loss and dispersion [1].

Ultrafast optical parametric amplifiers
Review of Scientific Instruments, 2003Over the last decade there have been spectacular developments in ultrafast laser technology, due to the introduction of solid state active materials and of new mode-locking and amplification techniques. These advances, together with the discovery of new nonlinear optical crystals, have fostered the introduction of ultrafast optical parametric ...

semiconductor optical amplifiers
SPIE Newsroom, 1990Semiconductor laser amplifiers have now proved their ability to improve the performance of single-mode fiber communication systems, at least in the laboratory stage. After a brief background review of optical amplification in communication systems, the principle of operation and main device characteristics of semiconductor optical amplifiers are ...

IEEE Microwave and Guided Wave Letters, 1993
A quasi-optical amplifier suitable for Gaussian-beam applications is presented. The amplifier is based on the integrated horn antenna and uses polarization duplexing to isolate the output beam from the input beam. A prototype hybrid amplifier is reported with a measured gain of 10.5 dB at 5.92 GHz.

An optical discrimination amplifier
Optics Communications, 1974Abstract Measurements on an optical discrimination amplifier are presented which demonstrate its ability to increase the S/N ratio of single ultrashort pulses by 2 to 3 orders of magnitude. The amplifier consists of a series of amplifiers and dye cells such that for each dye-amplifier section the small-signal gain is less than one.
