本发明实现了包含通过蚀刻氧化铟锡阳极层而制造的波纹光子晶体结构的有机发光二极管的工作电压的降低。这是由于有机层的厚度部分减少所致。由于光子晶体效应对受限光的衍射，还可以提高光提取效率。电压的降低与制造的器件在恒定电流下发光效率的提高相结合。 (C) 2004 年美国物理研究所。
A reduction of the operating voltage is achieved for an organic light-emitting diode containing a corrugated photonic crystal structure fabricated by the etching of an indium-tin-oxide anode layer. This is due to a partial reduction in the thickness of the organic layer. The light extraction efficiency can be also improved due to the diffraction of confined light by the photonic crystal effect. The voltage reduction is demonstrated in combination with an improvement in the luminance efficiency at constant current for the fabricated device. (C) 2004 American Institute of Physics.
