摘要

摘要当平面发光波导中的单个点被激发时，一些被困在其中的光致发光光子到达其边缘。考虑到波导的上下表面泄漏和导波过程中的自吸收造成的光子损失，将多边形波导和弯曲波导的边缘收集光子的概率表示为激发点坐标的函数。假设发射是各向同性的，为简单起见，忽略散射和再发射事件。该模型可用于预测不同形状的发光波导在非均匀光照下的性能。

Extending the concept of edge collection function to polygonal and curved planar luminescent waveguides

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.
