A simple and low-cost fabrication method of controllable one-dimensional and two-dimensional photonic crystal arrays was reported in this paper by the means of e-beam lithography with reactive Ion etching. We employed efficient etching process which could improve accuracy control in the sizes, period, and surface morphology of photonic crystal arrays. Based on these advantages, the high-performance distributed feedback polymer lasing cavity has been fabricated. The optical pumping results show that we have successfully achieved a lasing from organic laser dye with a low amplified spontaneous emission threshold of 260 kW/cm2 and a narrow full width half maximum of 0.22 nm.
