我们解决了从高折射率材料中尽可能有效地提取光的问题，n大于或等于2，其中由于临界角类似于1/n的小角度，只有2%-10%的未遭受全内反射的光在标准平面上被提取。使用平面微腔将自发辐射重定向到表面建设性干涉可以产生15%-50%的光输出，从而提高了亮度和效率。在这两篇论文中的第一篇中，使用了一种近似方法来说明小腔阶数m(E)和m(C)/n(2)比的重要性。我们定义了微腔体制的一个条件为m(C)
We address the long-standing issue of extracting light as efficiently as possible from a high-index material, n greater than or equal to 2, where as little as 2%-10% of light not suffering total internal reflection is extracted at standard plane faces due to the small critical angle similar to 1/n. Using a planar microcavity to redirect spontaneous emission toward the surface constructive interferences can bring 15%-50% of the light out, enhancing brightness and efficiency. In this first of two papers, an approximate approach is used showing the importance of small cavity order m(e) and of the m(c)/n(2) ratio. We define a condition for microcavity regime as m(c)
