Microfluidic lenses are relevant optical components for sensing application in lab-on-a-chip devices, guaranteeing a robust alignment of the elements, a high level of compactness and tunable optical properties. In this work we describe an innovative integrated in-plane microfluidic lens. The device shows both an optimized shape capable of reducing spherical aberrations and periodically tunable optical properties. Indeed through the combination of the lens with a droplet generator module, we have been able to obtain an integrated optofluidic modulator capable of both on-demand on/off switching and periodic modulation of light. The device possesses a simple 3D geometry, which has been realized by exploiting the 3D capability of the femtosecond laser micromachining fabrication technique.
微流体透镜是用于芯片实验室设备传感应用的相关光学组件，可确保元件的稳固对准、高度紧凑性和可调光学特性。在这项工作中，我们描述了一种创新的集成平面内微流体透镜。该器件既具有能够减少球差的优化形状，又具有周期性可调的光学特性。实际上，通过将透镜与液滴发生器模块相结合，我们能够获得一种集成光流体调制器，它既能按需进行光的开/关切换，又能对光进行周期性调制。该器件具有简单的三维几何形状，这是通过利用飞秒激光微加工制造技术的三维能力实现的。
