Only an arbitrary single pulse among pulse train with temporal separation of about 1 ps was trapped by soliton pulse,the trapped pulse was blue-shifted and the optical spectra of trapped pulse was distinctly separated from those of the untrapped signal pulses.The trapped pulse can be easily picked off using a wavelength filter such as a fiber Bragg grating.

通过数值求解光子晶体光纤中脉冲传播满足的耦合非线性薛定谔方程，发现用孤子脉冲可俘获信号脉冲串中的任何一个脉冲，被俘获的信号脉冲的中心波长明显蓝移，在频域上和其他信号脉冲分离开来，于是让信号脉冲串在输出端通过布喇格光纤光栅，被俘获的信号脉冲将被过滤掉。

Vadim Backman, PhD, a professor of biomedical engineering at Northwestern University in Evanston, Illinois, and colleagues, recently developed the 2 complementary optical techniques that were used in the study. The 4-dimensional elastic light-scattering spectroscopy (4D-ELF) and low-coherence enhanced backscattering spectroscopy use the elastic light-scattering signals from tissue that exhibit characteristic structure-dependent signatures in wavelength and scattering angle, explain the researchers in their paper.
