Beschreibungen/Notizen

• Dye-doped polymer microdroplet resonators were fabricated by injecting dye solutions into a low refractive index UV curable polymer. The self-assembled microdroplets had the various sizes ranging from 5 to 200 μm. Pumped by a pulse laser, whispering-gallery-mode (WGM) lasing emission from the microresonators was achieved. Experimental results show that the microresonators had the advantages of high-Q factors, low lasing thresholds, and good long-term stabilities. The injection method can provide a promising approach for fabricating the high-Q WGM microresonators, which had some potential applications in the fields of tunable microlasers and on-chip biosensing system.
