我们提出并实现了基于InP-InGaAsP独立板的光子准晶体（PQC）单细胞谐振器。从PQC单细胞谐振器中识别出C-6v对称的定义良好的六极类局域态。在这种类型的六极子模式中，电磁能量强烈地集中在介电区域，而在三角形晶格光子晶体中则相反。通过调整结构参数，六柱模态的最大理论质量因子接近2万。PQC单细胞谐振器在室温下以六极模式发光，阈值接近0.6 mW。(C) 2005美国物理研究所。(DOI: 10.1063/1.1852716)
We propose and realize the photonic quasicrystal (PQC) single-cell resonator based on a InP-InGaAsP freestanding slab. A well-defined hexapole-like localized state following a C-6v symmetry is identified from the PQC single-cell resonator. In this type of hexapole mode, the electromagnetic energy is strongly concentrated on the dielectric region, in contrast to that in a triangular lattice photonic crystal. By tailoring the structural parameters, the hexapole mode shows a maximum theoretical quality factor of similar to20 000. The PQC single-cell resonator lases in a single hexapole mode with a threshold of similar to0.6 mW at room temperature. (C) 2005 American Institute of Physics. [DOI: 10.1063/1.1852716]
