研究了具有多维光约束的微腔中的复模结构。我们的活性材料由有机混合物Alq(3): DCM组成，嵌入到包含光子线阵列的微腔中，促进强侧向约束。我们直接记录一个(k)右箭头矢量分量的能量色散，同时扫描第二个横向(k)右箭头分量。因此，我们获得了腔共振的详细色散层析图，与我们的光学模型非常吻合。我们能够超越激光阈值，不仅从腔抛物线的底部观测到受激辐射，而且从高阶模式观测到受激辐射。(c) 2013 AIP出版有限责任公司
We investigate the complex mode structure in microcavities with multidimensional optical confinement. Our active material is composed of the organic blend Alq(3): DCM, embedded into a microcavity containing arrays of photonic wires, facilitating strong lateral confinement. We directly record the energy dispersion for one (k) over right arrow vector component while the second lateral (k) over right arrow component is scanned. Thereby, we obtain a detailed dispersion tomogram of the cavity resonances, showing excellent agreement with our optical model. We are able to exceed the lasing threshold and observe stimulated emission not only from the bottom of the cavity parabola, but also from higher order modes. (c) 2013 AIP Publishing LLC.
