Polymer microlasers with a suspended cavity design

Polymer microlasers with a suspended cavity design

We report on the fabrication of microlasers with suspended cavity design in a thin layer of Rhodamine B doped SU-8 polymer using proton beam writing. Optical characterization of the fabricated three-dimensional microlasers under ambient atmosphere results in low lasing threshold of 0.5 μJ/mm2, which...
