Abstract
A simple method for complete characterization of periodic optical pulses based on time domain interferometry is demonstrated. The method does not require the use of an interferometer. A chirped fiber Bragg grating is used for stretching the pulses to be characterized. The interference between the stretched overlapped pulses is recorded by a photodiode and a sampling oscilloscope. The phase response of the chirped fiber Bragg grating is measured by an all-fiber Michelson interferometer. A fast-Fourier-transform method is used for processing of interference patterns in both the time and spectral domain.
