Abstract
An optically pumped waveguide structure has been fabricated with methy l substituted conjugated laddertype poly(paraphenylene) as the active material. The choice of the device parameters allows one to observe a high directionality, a small beam divergence, a complete linear polari zation, and a linewidth with an upper limit of 1.7 nm at a considerabl e low threshold of 3 kW/cm(2) at room temperature.
