(a) Relative spectral noise density of light intensity fluctuations as a function of the current for the LED-C. The open symbols show the light intensity noise when the entire LED spectrum is included in the noise measurements. The filled symbols are the integrals obtained from the measurements at different wavelengths assuming correlated (circles) and uncorrelated (triangles) fluctuations. The filled symbols are shifted left for clarity. (b) Current dependence of the relative spectral noise density of the LED current noise .
