Abstract :
A new and very simple method for the wavelength and line width measurement of optical sources with a resolution in the femtometre range is presented. Our method is based on the amplification of a backscattered wave by a pump wave due to Brillouin scattering. It requires neither a fast photodiode nor a spectrum analyser of any kind.
