Abstract

We studied the temperature dependence of the laser emission threshold in microring polymer lasers. For microring lasers with diameters between 16 and 120 μm, a weak temperature dependence was observed when the temperature was varied between 300 and 10 K. These experimental results are explained within a four-level model. Our results suggest that a significant reduction of threshold can be achieved at low temperatures if the quality factor Q of the microcavities is improved.
