在这封信中，我们报告了一个“一步”的光学有源有机光子带隙（PBG）结构的制造技术，允许放大自发辐射效应和相应的频带变窄的发病。通过将染料罗丹明6G添加到标准全息聚合物分散的液晶预聚物混合物中实现了该结果。分析了染料的加入对聚合PBG结构光学性能的影响。这种光学活性的周期性结构发出的光谱已被研究作为激发能量的函数。
In this letter we report a “one-step” fabrication technique of an optical active organic photonic band gap (PBG) structure allowing the onset of the amplification spontaneous emission effect and narrowing of the corresponding band. This result has been achieved through the addition of the dye rhodamine 6G to a standard holographic polymer dispersed liquid crystal pre-polymer mixture. The effects of the dye addition on the optical properties of the polymerized PBG structure have been analyzed. The spectra emitted by this optically active periodic structure have been studied as a function of the excitation energy.
