In not-so-rare unfortunate cases, the bias results in a negative phase-noise spectrum, which is an obvious nonsense. Similar results are observed separately in three labs with instruments from the two major brands. We provide experimental evidence, full theory and suggestions to mitigate the ...
色散平坦渐减光纤交叉相位调制The effect of cross phase modulation (XPM) on pulse propagation and supercontinuum (SC) spectrum generation in a dispersion flattened and decreasing fiber is researched. The results indicated that XPM could enhance the SC spectrum generation and increase the generation ...

Moreover, it is possible to characterize the causal relations among variables on a distribution of time delays (i.e., a causal spectrum). This full causal description will be included in our future work. As described above, the first-order PCM method can be established as following definition...
Due to XPM, the probe is phase modulated along the fiber by the intensity modulation created by the pumps. The OSA at the fiber output simultaneously measures the spectra of both the pump and the probe. Figure 4.8.20 shows an example of the measured optical spectrum where the pump and the...

The power spectrum provides a compact representation of the scale dependence of the variability in time series. At multi-millennial time scales the spectrum of the Pleistocene climate is composed of a set of narrow band spectral modes attributed to the regularly varying changes in insolation from th...
