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.
