We present a single mode, single polarization, distributed feedback polymer dye laser, based on a short high order Bragg grating defined in a dye doped polymer layer between two secondary polymer layers. The Bragg grating is defined solely with standard I-line UV lithography. In this device we obtain single mode operation in a multimode structure by means of mode loss differentiation without using sub-wavelength structures. The laser is fabricated using micro-fabrication technology, is pumped by a pulsed frequency doubled Nd:YAG laser, and emits light in the chip plane at 551.39 nm, with a FWHM linewidth below 150 pm.
我们展示了一种单模、单偏振的分布反馈聚合物染料激光器，它基于在两个二级聚合物层之间的染料掺杂聚合物层中定义的短高阶布拉格光栅。该布拉格光栅仅通过标准的I线紫外光刻技术定义。在这个器件中，我们通过模式损耗差异在多模结构中实现了单模运行，而无需使用亚波长结构。该激光器采用微加工技术制造，由脉冲倍频Nd:YAG激光器泵浦，并在芯片平面内以551.39 nm发射光，半高宽线宽低于150 pm。
