Optofluidics is a rapidly advancing research field that utilizes the integration of photonics and microfluidics to achieve a number of novel functionalities in miniaturized devices and microsystems. The optofluidic techniques have enabled the development of new coherent light source on chip, novel sensing and imaging methods, and integrated lab-on-chip platforms for bio/chemical sensing. This talk will give an overview of our recent work on optofluidic droplet lasers. I will first introduce a reconfigurable integrated droplet laser platform which features controlled droplet generation, tuning, and regeneration. The design and fabrication process of this laser is of low-cost, highly scalable, and can be implemented on various materials. I will also discuss droplet lasers on-the-flow, exploiting multiphase microfluidics. Lastly, I will present our study on a novel surface gain geometry in the droplet laser, which utilizes the self-assembly process to deterministically introduce a monolayer gain at the liquid-liquid interface. All of these developments address the imminent needs in lasing enabled sensing and imaging applications, which can greatly advance point-of-care monitoring and testing.
