Pulse distortion in single-mode fibers. 3: Chirped pulses

摘要: The theory of pulse distortion in single-mode fibers is extended to include laser sources that suffer a linear wavelength sweep (chirp) during the duration pulse. transmitted expressed as Fourier integral whose spectral function given by an analytical expression closed form. rms width also Numerical examples illustrate influence chirp on shape and A somewhat paradoxical situation exists. input can be made arbitrarily short sufficiently large amount chirping, and, after fiber length, this chirped returns its original width. But at particular distance unchirped would only 2 times longer. Thus chirping improve rate data transmission 40%.
