Abstract :
Experimental data are presented which show for the first time that the back-scattered signals independently generated by stimulated Brillouin scattering in two separate optical fibres may be mixed to produce narrowband radio-frequency signals. This mechanism can be exploited for microwave generation and distributed temperature sensing.
