Abstract
Lasing from spherical microdroplets ejected into a liquid medium with lower refractive index is observed in a microchannel. A microfabricated device that combines the droplet production and excitation/detection has been utilized. Droplets of 50 μm-diameter containing a fluorescent dye were first detected and then excited through multimode fibers after their production at a T-junction. Images show intense lasing emission around the droplet rim. Spectra from the droplets exhibit morphology dependent resonances (MDRs) which are red shifted relative to the bulk fluorescence emission from the dyes. The dependence of resonant peak intensities on the pump beam power is nonlinear.
