Paper Abstract

An optical technique to generate a heterodyne carrier frequency suitable for electronic signal processing schemes in sensing applications is described. The technique exploits stimulated Brillouin scattering generated in birefringent optical fiber. Systems based on dual fiber and single fiber topologies are reported which yield 665 MHz and 10.8 MHz carrier frequencies, respectively. Experimental results, indicating the presence of output frequency instabilities, are reported, and the implications for future signal processing and sensing schemes based on stimulated Brillouin scattering are discussed.
