On-chip integrated lasers for biophotonic applications

Meeting the need of biomedical users, we develop disposable Lab-on-a-Chip systems based on commercially available polymers. We are combining passive microfluidics with active optical elements on-chip by integrating multiple solid-state and liquid-core lasers. While covering a wide range of laser emission wavelengths, the chips have the size of microscope cover slips and use optical and fluidic interconnects only. Here, we present our latest realizations of integrated optofluidic lasers using whispering gallery mode or distributed feedback laser cavities.
