Abstract

Lab-on-a-Chip (LoC) devices combining microfluidic analyte provision with integrated optical analysis are highly desirable for several applications in biological or medical sciences. While the microfluidic approach is already broadly addressed, some work needs to be done regarding the integrated optics, especially provision of highly integrable laser sources. Polymer optical fiber (POF) lasers represent an alignment-free, rugged, and flexible technology platform. Additionally, POFs are intrinsically compatible to polymer microfluidic devices. Home-made Rhodamine B (RB)-doped POFs were characterized with experimental and numerical parameter studies on their lasing potential. High output energies of 1.65 mJ, high slope efficiencies of 56 % , and 50 % -lifetimes of ≥900 k shots were extracted from RB:POFs. Furthermore, RB:POFs show broad spectral tunability over several tens of nanometers. A route to optimize polymer fiber lasers is revealed, providing functionality for a broad range of LoC devices. Spectral tunability, high efficiencies, and output energies enable a broad field of LoC applications.

摘要

微流控分析物供给与集成光学分析相结合的片上实验室 (LoC) 设备在生物或医学科学的几个应用中非常理想。虽然微流控方法已经得到广泛应用，但在集成光学方面仍需要做一些工作，特别是提供高度集成的激光源。聚合物光纤 (POF) 激光器代表了一种无需对准、坚固和灵活的技术平台。此外，POF 与聚合物微流控器件具有内在的兼容性。对自制的罗丹明 B (RB)-掺杂 POF 进行了实验和数值参数研究，以评估其激光潜力。从 RB:POF 中提取出 1.65 mJ 的高输出能量、56 %的高斜率效率和 50 %-≥900 k 次的寿命。此外，RB:POF 显示出几十纳米的宽光谱可调谐性。揭示了优化聚合物光纤激光器的途径，为广泛的 LoC 设备提供了功能。光谱可调谐性、高效率和输出能量使 LoC 应用领域广泛。
