Second, in order to carry out broadband transmission spectrum measurement, the fiber array is connected to a supercontinuum white-light-source (Leukos SM-30-450) and an optical spectrum analyzer (Ando AQ6317b). The wave analyzer, used to analyze the signals of RF range is called superheterodyne wave analyzer. Theoretically, an optical spectrum should show the power spectral density (PSD) as a function of wavelength or optical frequency. A diffraction grading in the spectrometer separates the incoming light into element-specific wavelengths and a corresponding detector measures the intensity of light for each wavelength. When the beat frequency matches intrinsic Brillouin frequency of the fiber υ B, we will get maximum of Brillouin spectrum.
