Paper Abstract

The performance of distributed feedback (DFB) polymer lasers was adjusted by changing the cavity coupling. The microcavity of DFB polymer lasers was fabricated by two-beam multi-exposure interference lithography. With the different angles between two gratings, the coupling strength of the cavity modes was controlled. Reducing the coupling strength of cavity modes, the threshold of the polymer lasers decreased. According to the experimental results, the azimuthally polarized output was changed by tuning the cavity coupling. This method provides a facile way to realize low threshold and azimuthally polarized DFB polymer laser.
