An all-in-fiber prototype optofluidic device was fabricated by femtosecond laser irradiation and subsequent selective chemical wet etching. Horizontal and vertical microchannels can be flexibly created into an optical fiber to form a fluidic cavity with inlets/outlets. The fluidic cavity also functions as an optical Fabry-Perot cavity in which the filled liquid can be probed. The assembly-free microdevice exhibited a fringe visibility of 20 dB and was demonstrated for measurement of the refractive index of the filling liquids. The proposed all-in-fiber optofluidic micro device is attractive for chemical and biomedical sensing because it is flexible in design, simple to fabricate, mechanically robust, and miniaturized in size.
通过飞秒激光辐照和随后的选择性化学湿法蚀刻制备了一种全光纤原型光流控器件。水平和垂直微通道可以灵活地创建在光纤中，以形成带有入口/出口的流体腔。该流体腔还充当光学法布里-珀罗腔，其中可以探测填充的液体。该无组装微器件的条纹可见度为20 dB，并用于测量填充液体的折射率。所提出的全光纤光流控微器件在化学和生物医学传感方面具有吸引力，因为它设计灵活、制造简单、机械坚固且尺寸小型化。
