ABSTRACT:
An optical signal generator, an optical communication system, and a method for searching for a Fresnel reflection point in an optical transmission line make use of characteristic features of stimulated Brillouin scattering (SBS). In the optical signal generator, exciting light supplied to an optical transmission line, formed of a nonlinear optical medium, showing stimulated Brillouin scattering, is amplitude-modulated with an information signal. The threshold value for stimulated Brillouin scattering in the optical medium is positioned between a high level and a low level of the modulated waveform.
