| 摘 要： | 利用多重散射法和时域有限差分法理论,研究了二维三角晶格光子晶体耦合腔光波导的传输特性.理论模拟结果表明,在耦合腔光波导中嵌入半径很小的理想金属丝,能有效地减弱相邻点缺陷之间的耦合强度,实现了比真空中光速小三个数量级的群速度. |

| Abstract: | The transmission characteristics of the coupled-resonator optical waveguides based on the two-dimensional triangular-lattice photonic crystal are studied by the multiple-scattering methods and the finite-difference time-domain method.Through selective inserting the rods with different radius between two adjacent microcavities,the coupling intensity between the two adjacent point defects is weaken,and the group velocity can be further reduced by three orders of magnitude. |
