Current technology is relatively mature optical amplifier has an erbium doped fiber amplifier (EDFA), optical fiber Raman amplifier (FRA) and a semiconductor optical amplifier (SOA).
Optical amplifier
Optical amplifiers are based on stimulated emission or stimulated scattering of incident light signal amplification principle to achieve a device. Optical amplifier in the structure is a smaller no feedback or feedback laser. Any optical media, when using the pump (electrical or optical) method, to be able to produce optical gain when the population inversion distribution that achieve optical amplification.
