我们演示了如何在一个单一的光子晶体结构中实现两个光学功能，通过仔细工程色散在几个不同的波段在几个不同的波长。我们使用的概念，光泵浦染料掺杂的混合聚合物带边激光器，并显示如何一个矩形的光子晶体晶格压印到表面可以提供反馈的面内带边激射和耦合到设备平面的泵浦光，从而增加了发射强度和降低激射阈值超过一个数量级。
We demonstrate how two optical functionalities can be implemented in a single photonic crystal structure by carefully engineering dispersion in several different bands at several different wavelengths. We use the concept for optically pumped dye doped hybrid polymer band edge lasers and show how a rectangular photonic crystal lattice imprinted into the surface can provide both feedback for in-plane band edge lasing and couple pump light into the device plane, thus increasing the emitted intensity and lowering the lasing threshold by more than an order of magnitude.
