The results show that the heterostructure photonic crystal can extend remarkably the photonic bandgap compared with the periodic structure;a defect is inserted into the heterostructure photonic crystal,the nontransmission band is wider than that of the symmetric structure without heterostructures,(1H1L)_m(1H)_n(1L1H)_m.

结果表明，与周期结构相比异质结构光子晶体可以显著地拓宽光子晶体的光子带隙；在该文提出的结构中引入缺陷，与(1H1L)m(1H)n(1L1H)m光子晶体相比，产生缺陷模式光子带隙范围明显拓宽，适当调整缺陷层的数目、位置和厚度可得到多通道滤波；并研究了实际操作中随机误差带来的影响，随无序度的增大，其带宽基本不变。

Based on the regional tectonic evolution, combined with the high precision isotopic ages from this paper and other geologists, we have some new acquaintances as follows: 1 There has no Caledonian granite belt distributed in north margin of North China Craton. So, the traditional evolving model of North China Carton, which formed on this idea and the acquaintance about the collision of North China plate and Siberian plate, must be incorrect; 2 The age date show that the earliest magmatic activity began since late-Palaeozoic Permian, which is inconsistent with the previous idea that there were Caledonian and Hercynian active continental margin in the north of North China Craton and in the south Xingkai Massif. 3 the crust and lithosphere were thickened by the subduction and collision of Siberia plate and North China plate during Late Paleozoic. The magma is formed when the crust is heated and melts caused by thickened lithosphere delamination and caused the Asthenosphere upwelling. But only a little basaltic magma erupted, most magma underplate under the bottom of the crust. Thermal energy derived from basaltic magma underplating made the middle and lower crust melt partially and the late Permian-early Triassic granites is formed in large scale.

根据区域构造演化分析，并结合本文及他人高精度同位素年龄，我们对延边花岗岩形成的大地构造环境有了新的认识：1在华北地台北缘并不存在所谓的加里东花岗岩带，因此，建立在此之上的传统的华北地台北缘演化模式及有关西伯利亚板块与华北板块的碰撞拼合的认识也必然是不正确的；2华北地台北缘和兴凯地块南缘不存在加里东期和海西期花岗岩带，表明两地块边缘最早的花岗质岩浆活动始于晚古生代的二叠纪，即不存在传统观点所认为的加里东期或海西期活动陆缘；3晚古生代由于西伯利亚板块与华北板块的俯冲碰撞，致使地壳和岩石圈增厚，导致加厚岩石圈发生拆沉作用，使得软流圈上涌，加热地壳使之熔融形成岩浆，但玄武质岩浆少量喷出地表，大部分底侵于地壳底部，形成下地壳高密度的玄武质底侵层，玄武质岩浆底侵的热能引起中下地壳广泛部分熔融，形成大面积分布的晚二叠世—早三叠世花岗岩。

The intensity ratio of TO and LO inMCT was observed to be different. Such difference was explained in terms of the different Ramangeometry arrangement.〓. The laser-induced micro-photoluminescence in the range of 1000～5000〓(1.34eV～1.83eV) was found for the first time in LPE MCT epilayer. The center of photoluminescence wasat 2750〓 or 1.62eV and the FWHM of luminescence was 2000〓 or 0.25eV. We assume thatthe photoluminescence is due to recombination of electron from an anion vacancy resonance levelto the top of valance. In addition, new Raman shift was observed at 750〓 in LPE MCTepitaxial film.〓. The laser-induced micro-photoluminescence with quasi-periodic structure was observed forthe first time at room temperature in one of MOVPE MCT epitaxial film samples. The range offluorescence was from 1.46eV to 2.21eV, i.e., 1.73eV above the conduction band edge.

2首次在LPE生长的碲镉汞外延薄膜的显微Raman谱中，在1000～5000〓范围发现了激光激发显微荧光，该荧光的发光范围换算为电子伏特标度为1.34eV～1.83eV，荧光的发光中心大约位于2750〓，即1.62eV，发光的半峰高宽约为2000〓或0.25eV；指出该显微荧光来源于碲镉汞薄膜中的阴性离子空位共振能级的激光激发发光；观察到了碲镉汞外延薄膜中一个新的Raman散射峰，位于750〓位置； 3首次在一块用MOVPE方法生长的〓Te外延薄膜的显微Raman谱中，发现了1.46eV至2.21eV范围并伴随有周期结构的显微荧光峰，该发光峰对应的能带中心位于〓Te材料导带底上方1.73eV，通过研究得出样品在1.46eV至2.21eV范围的显微荧光峰是由于改进 MOCVD 生长工艺，提高了碲镉汞外延薄膜的结构质量所致；通过分析指出该显微荧光来源于外延层中的阴性离子空位的共振能级发光。
