In addition, the proposed PCF also has double zero dispersion points when wavelength range from 0.8μm to 2μm.
The measures of central tendency and dispersion pointed out reasonable spatial variability in Ks distribution throughout the study reach during two consecutive years 2016 and 2017.
Aiming at the requirements of high birefringence and double zero dispersion points in optical sensing and optical communication, a new kind of photonic crystal fiber (PCF) with hybrid structure is proposed, of which the cladding is arrayed in octagonal and squarely cladding.
To analyse the origin of modes, the spatial distribution of the electric field intensity for dispersion points marked by circles in Fig. 2 is presented in the Fig. 3 for s-polarization and Fig. 4 for p-polarization in the case of various numbers of layer pairs forming Bragg mirror.
From Figure 3, we find not only the blockade currentamplitude and duration time but also the event point dispersion degree increase with theincreasing Mg2+ ion concentration.
We conclude that the number of zero-dispersion points in the dispersion profile of a fiber is an excellent predictor of the dispersive-wave peaks when it is pumped with femtosecond pulses in the anomalous dispersion regime.
The coexistence of liquid liquid and liquid solid transitions at the same temperature range confirmed the complex behavior of the polyurethane dispersions, pointing to the need for a new theory that explicitly takes this special behavior into account.
Some factors such as multiple scattering points and dispersion make echo waveforms seriously distorted in ultra-short pulse radars; hence, the backscattered signal from a target upon impingement of an ultra-short pulse signal has a complex shape in time domain and is completely different from the transmitted waveform [5].
The standard methodology for identifying a dispersion end point is the determination of the point where particle size distributions plateau or do not significantly change with energy input (Taurozzi et al. 2011).
A fiber-optic long-period grating (LPG) operating near the dispersion turning point in its phase matching curve, referred to as a turn-around-point (TAP LPGG, is known to be highly sensitive to external parameters.
