Semiconductor Optical Amplifiers (SOAs) are now commercially available, with rather attractive features in both 1300 and 1550 nm wavelength windows: fiber- to-fiber gains ranging from 25 to 30 dB, polarization sensitivity below 1 dB, saturation output powers up to 13 dBm, noise figures around 6-7 dB and a smooth, large optical bandwidth of 50 nm. In addition, they could be integrated on small chips with a lot of other InP based components, and fabrication technology is quite compatible with mass production, a key step towards low prices. So, why can't we find any of these devices in optical networks?
