Abstract :
We report laser action from conical polymeric microcavities. A thin film of the organic semiconductor tris(8-hydroxyquinoline) aluminum (Alq3) doped with the laser dye 4-dicyanmethylene-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran (DCM) on top of the microcones enables low-threshold lasing when pumped with a conventional blu-ray laser diode. This combination might pave the way towards compact, low-cost integrated laser-based sensing systems.
