Basic principle of EDFA A relatively high-powered beam of light is mixed with the input signal using a wavelength selective coupler (WSC).
It can be potentially less expensive than the EDFA and can be integrated with semiconductor lasers, modulators, etc. However, the performance is still not comparable with the EDFA.
The gain spectrum of the EDFA has several peaks that are smeared by the above broadening mechanisms.
