Lasing from all-polymer microcavities

What is it about?

ABSTRACT We report on the laser action in a microcavity where both the dielectric mirrors and the active material have a macromolecular nature, resulting in a full plastic laser device. Distributed Bragg reflectors (DBRs) are prepared by spin-coating of polyvinylcarbazole and cellulose acetate orthogonal solutions and the active layer consists of a highly fluorescent conjugated polymer (F8BT) film. A quality factor in the range 80–180 is achieved. Laser thereshold is <20 microJ/cm2

Why is it important?

Free-standing laser cavity (both mirrors and active materials) can be easily prepared and tuned in different spectral ranges
