Within the associated framework of metal-dielectric films optics and the dual-metal-mirror mnicrocavity structure, the effect of a cladding dielectric layer on the light outcoupling efficiency of the top emitting orgainic light-emitting devices (OLEDs) is analyzed. A combined evaluation followed by detailed design and optimization is proposed and described in detail. The analysis shows that this cladding layer affects the device's outcoupling efficiency with three different extents as the thickness of the metal layer in the multilayer cathode varying. The simulation results give a reasonable agreement with former experiment results. 相似文献

用薄膜光子晶体超晶格概念设计多峰滤光片 总被引:1,自引:0,他引:1
多峰滤光片在光通讯波分复用技术中潜在着特殊的应用。利用薄膜一维光子晶体超晶格的概念,设计了两种薄膜多峰滤光片。第一种是基于两个一维光子晶体迭加的多峰滤光片,它在交叠的禁带上出现多组通带,每组通带又包含着多个透射峰,峰的数目为两个光子晶体的周期数减去1;第二种是在第一个光子晶体的中间插进第二个光子晶体,因而形成三个基本周期的光子晶体迭加,峰的数目主要取决于插入的第三个光子晶体的膜层厚度之比和周期数。讨论了多峰滤光片的通带特性和截止度。 相似文献
