We investigate the change of the photonic band structure of the Suzuki-phase photonic crystal lattice when the horizontal mirror symmetry is broken by an underlying Bragg reflector. The structure consists of an InP photonic crystal slab including four InAsP quantum wells, a SiO(2) bonding layer, and a bottom high index contrast Si/SiO(2) Bragg mirror deposited on a Si wafer. Angle- and polarization-resolved photoluminescence spectroscopy has been used for measuring the photonic band structure and for investigating the coupling to a polarized plane wave in the far field. A drastic change in the k-space photonic dispersion between the structure with and without Bragg reflector is measured. An important enhancement on the photoluminescence emission up to seven times has been obtained for a nearly flat photonic band, which is characteristic of the Suzuki-phase lattice.
我们研究了在底层布拉格反射器破坏水平镜面对称性时，铃木相光子晶体晶格的光子带结构变化。该结构由一个包含四个InAsP量子阱的InP光子晶体平板、一个SiO₂键合层以及沉积在硅片上的底部高折射率对比度Si/SiO₂布拉格镜组成。角度和偏振分辨光致发光光谱已被用于测量光子带结构以及研究与远场中偏振平面波的耦合。测量了有无布拉格反射器的结构之间k空间光子色散的剧烈变化。对于具有铃木相晶格特征的近乎平坦的光子带，光致发光发射获得了高达七倍的重要增强。
