Paper Abstract

An analysis of the spectrum of optical pulses by dispersion-time spectrum analyzer and a diffraction grating spectral device is considered. A theory of the dispersion-time spectrum analyzer of single optical pulses is proposed, which is an optical analog of the dispersion-time method for measuring spectra of radio signals, and the optical fiber is used as the dispersive medium. A computer simulation of the evolution of a monochromatic pulse propagating in a dispersive system in optical fiber is performed, which makes it possible to determine its minimum length and the dynamics of analysis of the instantaneous spectrum of a single optical pulse when the spectrum is measured by a diffraction optical spectral device.
