Abstract :
Focusing properties of a novel type photoresist microlens are studied. A specific character of the microlens is its mushroom shape. Recently, it has been predicted and experimentally revealed that such a lens integrated with a light-emitting diode is capable of enhancing the output efficiency and directivity. In our paper, we analyze the electromagnetic performance of the mushroom lens by applying a mathematically rigorous method of boundary integral equations. Numerical results are presented for the mushroom lens illuminated with a plane E-polarized wave and include figures describing the evolution of the lens focal spot and near field maps
