摘要
In this work, we demonstrated, both experimentally and numerically, the existence of a chirp-free pulse propagation regime within a standard single-mode fiber. We found numerically that the pulse spectrum can undergo self-compression by more than a hundredfold, resulting in the creation of a spectrally limited pulse. In this regime, we experimentally achieved a 5× spectral self-compression, reducing the spectral width from 75 nm to 15 nm within the 1.3–1.5 μm spectral range. This was achieved with a standard telecommunication fiber with constant dispersion.
