我们证明了有机半导体激光器作为芯片实验室系统光源的可行性。这些激光器基于1D或2D光子晶体谐振器结构，其在沉积在顶部的有源激光器材料中提供光学反馈，所述有源激光器材料例如掺杂有激光染料4-二氰基亚甲基-2-甲基-6-（对二甲基氨基苯乙烯基）-4H-吡喃（DCM）的三（8-羟基喹啉）铝（Alq 3）。我们研究了不同的制造方法的谐振器结构，如热纳米压印，紫外纳米压印，和激光干涉光刻。部署了芯片实验室系统中常用的不同基底材料，例如PMMA、Topas和Ormocer。通过改变分布反馈光栅的周期性，我们证明了一个单一的材料系统的调谐范围超过120 nm。所研究的有机半导体激光器是光泵浦的。外部光抽运技术为一次性芯片提供了一条可行的途径。我们最近用低成本激光二极管泵浦有机激光器的成功也使手持系统成为可能。作为对传感器系统中的有机激光器的集成的进一步步骤，我们展示了有机激光器到聚合物波导，可以与微流体通道相结合的耦合。集成的有机激光器和波导都制作在同一个抛光的PMMA基板上，分别使用热纳米压印光刻和深紫外改性。我们可以演示激光在单模波导中的导引。
We demonstrate the feasibility of organic semiconductor lasers as light sources for lab-on-a-chip systems. These lasers are based on a 1D- or 2D-photonic crystal resonator structure providing optical feedback in the active laser material that is deposited on top, e.g. aluminum tris(8-hydroxyquinoline) (Alq3) doped with the laser dye 4-dicyanomethylene-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran (DCM). We investigated different fabrication methods for the resonator structures, like thermal nanoimprint, UV nanoimprint, and laser interference lithography. Different substrate materials commonly used in lab-on-a-chip systems, e.g. PMMA, Topas, and Ormocer were deployed. By changing the distributed feedback grating periodicity, we demonstrate a tuning range for a single material system of more than 120 nm. The investigated organic semiconductor lasers are optically pumped. External optical pumping provides a feasible way for one-time-use chips. Our recent success of pumping organic lasers with a low-cost laser diode also renders hand-held systems possible. As a further step towards the integration of organic lasers in sensor systems, we demonstrate the coupling of an organic laser into polymeric waveguides which can be combined with microfluidic channels. The integrated organic lasers and the waveguides are both fabricated on the same polished PMMA substrate using thermal nanoimprint lithography and deep-UV modification, respectively. We could demonstrate the guiding of the laser light in single-mode waveguides.
