For the continuous-wave semiconductor (AlGaAs) distributed feed back lasers (DFB) used in telecommunication technology today a nonlinear refractive index n2=S cm2/GW would be necessary for all-optical switching, which is presumably impossible to reach. Including an Erbium doped fiber amplifier (EDFA) the needed nonlinearity drops only by a factor of ten. [Pg.140]

SEMICONDUCTOR OPTICAL AMPLIFIERS have received less attention in the literature than amplifiers using optical fibers as the gain medium. Fiber amplifiers, including Erbium-doped fiber amplifiers and Raman amplifiers are currently transforming the world of optical fiber telecommunications as they become incorporated as line amplifiers in high-capacity wavelength-division multiplexed (WDM) transmission systems. However, despite the dominance of fiber amplifiers in the telecommunications marketplace, semiconductor optical amplifiers continue to show potential for application in a range of... [Pg.196]

Thus, for even the very best possible high-gain amplifier with complete inversion (Usp = 1), the noise figure F is never less than 2 (3.01 dB). This is a fundamental result for an IMDD system that can be arrived at more generally using Heisenberg s uncertainty principle as the starting point. While this so-called quantum limit has been approached in other types of optical amplifier (most notably erbium-doped fiber amplifiers), it is never achieved in SOAs because, as Fig. 9 shows, the spontaneous emission factor never reaches the theoretical limit of Usp =. ...

The transmission distance in optical fiber communications has been greatly increased by the development of erbium-doped fiber amplifiers. Consequently, the main factor limiting the maximum repeater span is now the fiber... [Pg.269]
