3-D Self-Assembling Point-Source Microlasers
Tiny spherical drops in liquid self-organize into lasing cavities that demonstrate low threshold, emit in all directions, and can be designed with wavelengths from ultraviolet to infrared.
A cut-away view of a microlaser droplet. The reddish center represents lasing dye molecules, while the radial yellowish helices indicate cholesteric liquid crystal molecules.
Tiny spherical drops in liquid self-organize into lasing cavities that demonstrate low threshold, emit in all directions, and can be designed with wavelengths from ultraviolet to infrared. These lasers are made of droplets of dye-doped cholesteric liquid crystals (CLCs) suspended in a carrier fluid (Opt. Express 18, 26995), and they are part of a long-term project on soft-matter photonic devices carried out in Igor Musevic's lab at the J. Stefan Institute and University of Ljubljana, Slovenia.
