在薄壁管中引入预折叠图案已被证明可以有效增强其能量吸收能力.然而,仅仅靠预折叠图案设计所提高的能量吸收能力已经达到天花板,难以进一步提高。本研究为解决这一问题,提供了一种全新的技术路线.我们首先设计了一种结构均匀的预折叠薄壁管作为参考结构.然后,我们对参考结构的壁厚进行非均匀化设计。在保持薄壁管总质量不变的情况下,加厚了塑性变形相对较大的局部区域的壁厚,同时变薄了塑性变形相对较小的局部区域的壁厚。这种非均匀设计方式使薄壁管的整体变形更加协调,不仅显著提高了结构的比吸能(SEA),而且降低了峰值力(pcf),实现了SEA和pcf的更优组合.

This work presents a numerical investigation of the self-steepening（SS） effect on the soliton spectral tunneling（SST） effect in a photonic crystal fiber（pcf） with three zero dispersion wavelengths. Interestingly, the spectral range and flatness can be flexibly tuned by adjusting the SS value. When the SS coefficient increases, the energy between solitons and dispersion waves is redistributed, and the red-shifted soliton forms earlier in the region of long wavelength anomalous dispersion. As a consequence, the SST becomes more obvious. The findings of this work provide interesting insights in regard to the impact of the SST effect on tailored supercontinuum generation.

A photonic crystal fiber based surface plasmon resonance(pcf-SPR)sensor is simulated by finite element method and experimentally realized.The calculations show that there is an obvious loss peak in the vicinity of 1.2μm while the pcf of LMA-8 is used as a sensor.The suspension of silver nanoparticle mixed with hexadecyl trimethyl ammonium bromide (CTAB)is inhaled into the pcf to form a metal film which can be stimulated to generate plasmon in the experiment.A spectrometer is utilized to detect the continuous broadband transmission spectrum from the pcf.The experimental results verify the loss peak.Compared with the theoretical calculations,the offset of loss peak about 40 nm can be acceptable, because the uniformity of the metal coating is difficult to guarantee and the film thickness is difficult to control.

A stable three-channel dual-wavelength fiber ring laser is proposed and experimentally demonstrated. The dig- ital mieromirror-deviee （DMD） processor can select and reeirculate any dual waveband from the gain spectrum of the erbium-doped fiber at each channel. The uniform and stable dual-wavelength oscillation is obtained by a highly nonlinear photonic crystal fiber, which causes two degenerate the four-wave-mixing processes. By loading different reproducibility diffraction gratings on the optoelectronic DMD processor, the laser can be operated stably in a three-channel dual-wavelength scheme at room temperature. The power fluctuation of each laser channel is less than -0.02 dB.

Long-period gratings （LPGs） are fabricated in a photonic crystal fiber （pcf） using the symmetric point- by-point CO2 laser irradiation method to explore the sensitivity characterization of pcf-LPG. Numerical sim- ulation is used to guide the investigation. It is found that the refractive index （RI） sensitivity of pcf-LPG depends on the coupled cladding modes as well as the coupled resonance wavelength （RW） of the LPG. Experimental studies show that the longer the RW, the higher the RI sensitivity for the same cladding mode. At similar RWs, the lower the cladding mode, the higher the RI sensitivity of pcf-LPG.

We propose a novel all fiber Mach-Zehnder interferometer（MZI） based on photonic crystal fiber（pcf） filled with liquid crystal（LC）. The interference between the core mode and the cladding modes of a pcf is utilized.To excite the cladding modes, a region is formed using fiber fusion splicer. Due to the fact that varying effective index difference between the core region and the LC-filled cladding region can cause different transmission spectra,we mainly study the MZIs with different LC-filled structures and different lengths of LC filling. The measured results demonstrate that quite clear interference spectra can be obtained. Through analysis spatial frequency spectrum and temperature spectrum of two MZIs with different LC-filled structures, we can obtain that the MZI with adjacent two LC-filled holes has clearer interference spectrum and higher temperature sensitivity. Thus we choose this MZI to measure the temperature sensitivity with different lengths of LC filling. When the length of LC filling is 2 cm, the temperature sensitivities can be enlarged to 1.59 nm/C. The interferometer shows a good temperature tunability and sensitivity, which can be a good candidate for a highly tunable optical filtering and temperature sensing applications.
