双乳液液滴在生物传感、化学合成、药物输送和高通量筛选和生产中有着广泛的应用。在这项工作中，我们展示了单分散双乳液光流体微激光器与染料掺杂薄壳结构。特别地，证明了水包油包水（W/0/W）双乳液液滴在流体动力学流动聚焦微流体装置中的稳健产生。通过在双乳液中仔细布置三种液体组分，形成光学微腔，其支持位于壳层表面附近的回音壁模式（WGM）。在W/O/W双乳胶液滴中实现了低阈值激光输出。研究了不同粒径和不同壳层厚度的双乳胶液滴在流动中的激光发射特性。由于微流体装置提供的高度控制，可以方便地调节液滴尺寸和壳层厚度，从而调节激光特性。双乳液液滴独特的两相核壳结构为基于本工作中展示的光流体激光系统的生物传感平台的开发提供了极大的灵活性和潜力，特别是在高通量生物分析中。
Double emulsion droplets have found diverse applications in biosensing, chemical synthesis, drug delivery, and highthroughput screening and production. In this work, we demonstrate monodisperse double emulsion optofluidic microlasers with a dye-doped thin shell structure. In particular, robust generation of water-in-oil-in-water (W/O/W) double emulsion droplets in a hydrodynamic flow focusing microfluidic device is demonstrated. With careful arrangement of the three liquid components in the double emulsion, an optical microcavity is formed which supports the whispering gallery modes (WGMs) that locate near the surface of the shell layer. Low-threshold lasing has been achieved in W/O/W double emulsion droplets. Lasing emission from double emulsion droplets with different diameter and different shell layer thickness are characterized on the flow. Due to the high degree of control provided by the microfluidic device, both droplet size and shell layer thickness can be conveniently tuned, and thus the lasing properties. The unique two-phase core-shell structure of the double emulsion droplets provides great flexibility and potential in the development of biosensing platform based on the optofluidic laser system demonstrated in this work, especially in the high-throughput bioanalysis.
