Abstract

International audience; We experimentally and theoretically analyze an original method based on two-wave mixing in an erbiumdoped fiber amplifier for optical carrier reduction of microwave signals. 75% optical carrier attenuation has been observed, and a 10 dB modulation depth increase of the microwave signal is experimentally demonstrated. Moreover, calculated results are in good agreement with measurements and predict that up to 80% carrier attenuation is easily possible.

Abstract

A solution for dynamically enhancing the modulation depth of optically carried microwave signals is presented. It is based on stimulated Brillouin scattering in photonic crystal fibres (PCFs) used in loop configuration. The behaviour of this nonlinear effect in this new type of fibre is compared, both experimentally and theoretically, to that observed in conventional optical fibres.
