Lorentzian Spectrum. A light-emitting diode (LED) emits light of Lorentzian spectrum with a linewidth Av (FWHM) = 1013 Hz centered about a frequency corresponding to a wavelength A, = 0.7 µm. Determine the linewidth AA, (in units of nm), the coherence time Te, and the coherence length le. What is the maximum time delay within which the magnitude of the complex degree of temporal coherence [g(t)| is greater than 0.5?
