Implication

Experimental study demonstrates low-threshold microfluidic lasers using fluorescence resonant energy transfer, highlighting opportunities for intracavity biochemical sensing.

Key Points

To develop and evaluate an optofluidic ring resonator dye laser operating via highly efficient energy transfer mechanisms.
Constructed a ring resonator using a fused silica capillary supporting high Q-factor (>10^7) whispering gallery modes.
Flowed donor-acceptor mixtures through the capillary, utilizing fluorescence resonant energy transfer to couple acceptor emission into optical modes.
Tested cascade energy transfer schemes and quantum dots as alternative donor systems while analyzing non-radiative Förster transfer dynamics.
Achieved an acceptor lasing threshold as low as 0.3 µJ/mm² facilitated by high transfer efficiency and optical cavity Q-factors.
Identified non-radiative Förster transfer as the primary underlying mechanism driving acceptor lasing.
Demonstrated flexible multi-wavelength excitation and emission using cascade energy transfer and quantum dot donors.
