aWe consider a 40-ps full-width at half maximum (FWHM) Gaussian pulse at 1.55 m wavelength, chirped by propagation through a 100-km length of fiber, that is incident on a uniform Bragg grating. By detuning the center frequency of the dispersion broadened pulse from the resonant frequency of...
Additionally, data analysis techniques such as fitting the emission peaks with Gaussian or Lorentzian functions can be used to determine the FWHM. Overall, the FWHM in a PL spectrum is an important parameter that provides valuable information about the emission properties of a material and can be ...
