我们研究了利用二维光子晶片来改善平面光波导和分布反馈激光器输出耦合的方向性。我们介绍了这种结构运行的基本理论和在所需方向上排放的设计标准。作为一个例子，我们展示了一种与有机分布反馈激光器集成的垂直耦合器，利用计算机模拟得到了它的耦合常数和效率，并讨论了它的可行性。
We investigate the use of two-dimensional photonic crystal slabs to improve the directionality of output coupling from planar waveguides and distributed-feedback lasers. We present the theory underlying the operation of such structures and design criteria for emission in desired directions. As an example, we demonstrate a vertical coupler that is integrated with an organic distributed-feedback laser, use computer simulations to find its coupling constant and efficiency, and then discuss its feasibility.
