Abstract
An optical technique for producing a heterodyne carrier frequency suit able for electronic signal-processing schemes in sensing applications is described. The technique exploits stimulated Brillouin scattering ( SBS) generated in birefringent optical fiber. Systems based on single- fiber and dual-fiber topologies are reported that yield 10.6 +/- 8.0- and 665 +/- 10.0-MHz carrier frequencies, respectively. Frequency inst abilities arose from nonlinear dynamical effects inherent to the SBS p rocess. The implications of the results for future signal-processing a nd sensing schemes based on SBS are then discussed.
