Abstract :
A system for analyzing low frequency light fluctuation is set up with a multi-channel detector and a few results are shown. The multi-channel detector includes a PCD image sensor which has 256 sensing elements. The light output of a laser diode is divided into various wavelengths and the light spectral intensities are obtained at various wavelengths. The current noise is also measured. The noises show 1/f spectra. The correlation coefficient between the light and the driving current is calculated from the measured values
