Abstract. When a single spot in a planar luminescent waveguide is excited, some photoluminescence photons that are trapped inside reach its edge. Considering the photon losses due to leakage from its top and bottom surfaces and self-absorption during wave-guiding, the probability of collecting photons at its edge is expressed as a function of the coordinates of the excited spot for polygonal and curved waveguides. The emission is assumed to be isotropic, and scattering and re-emission events are neglected for simplicity. This model might be useful for predicting the performance of luminescent waveguides with various shapes under non-uniform illumination.

将边缘收集功能的概念扩展到多边形和弯曲平面发光波导

摘要。当平面发光波导中的单个光点被激发时，一些被困在内部的光致发光光子到达其边缘。考虑到由于从其顶部和底部表面泄漏以及波导过程中的自吸收而导致的光子损失，在其边缘收集光子的概率表示为多边形和弯曲波导的激发点坐标的函数。假设发射是各向同性的，并且为简单起见忽略了散射和再发射事件。该模型可能有助于预测在非均匀照明下具有各种形状的发光波导的性能。
