Paper Abstract

We present the results of a study of the optical properties of an organic dye, (1,4-Bis[2-[4-[N,N-di(p-tolyl)amino]phenyl]vinyl]benzene)-doped polymer for photonic device applications. We have measured considerable modal gains of up to 33 cm-1 at 501 nm at a range of pump fluences using the variable stripe length method. In addition, we have incorporated the material into a planar waveguide laser, which operates at a low-lasing threshold. The measured laser threshold agrees well with that predicted for a 1-cm Fabry-Perot type cavity. We have also made 80-micron diameter microrings, which operate at a low lasing threshold and exhibit lasing in a small number of narrow, well-defined cavity modes.
