Abstract

We demonstrate laser emission in polymer-based microrings doped with a near infrared emitting dye, 2-(6-(4-Dimethylaminophenyl)-2,4-neopentylene-1,3,5-hexatrienyl)-3-methyl-benzothiazolium perchlorat. We fabricate our poly(1-vinyl-2-pyrrolidone)-based microrings containing 0.5 wt % of the dye. They exhibit lasing at around 840 nm under transverse nanosecond photoexcitation at 532 nm. Optical feedback is provided by total internal reflection. The threshold for lasing is found to be 311 μJ/cm². The cavity has a Q-factor larger than 2000, which is limited by the resolution of our detection system.
