| 英文摘要 | Inspired by the idea of the stero-coupling, we propose a new sandwich-like photonic crystal microcavity which is composed of double layer photonic crystal slabs h1 (dlpcs-h1) cavity with an air layer in between. we calculate the electromagnetic field distribution and the quality factor of the dipole mode by the three-dimensional finite-difference time-domain method and the pade approximation method. through carefully analyzing the effect of the air layer height on the quality factor of the dipole mode, we obtain an optimized dlpcs-h1 cavity in which the height of intermediate air layer is about 0.5a (a is the lattice constant, a = 420 nm). in this cavity, the quality factor of the dipole mode is 4 times as large as that of the conventional single layer photonic crystal slab h1 cavity. furthermore, we study the three-layer photonic crystal slabs h1 cavity, and the quality factor of its dipole mode is increased over 7 times. |
