We present a single-mode, single-polarization, distributed feedback liquid dye laser, based on a short high-order Bragg grating defined in a single polymer layer between two glass substrates. In this device we obtain single-mode operation in a multimode structure by means of transverse-mode discrimination with antiguiding segments. The laser is fabricated using microfabrication technology, is pumped by a pulsed frequency-doubled Nd:YAG laser, and emits narrow-line-width light in the chip plane at 577 nm. The output from the laser is coupled into integrated planar waveguides defined in the same polymer _lm. The laser device is thus well suited for integration, for example, into polymer based lab-on-a-chip microsystems.
我们展示了一种单模、单偏振、分布反馈液体染料激光器，它基于在两个玻璃基板之间的单个聚合物层中定义的短高阶布拉格光栅。在该器件中，我们通过使用具有反导段的横向模式鉴别，在多模结构中实现了单模运行。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577nm发射窄线宽光。激光器的输出耦合到在同一聚合物薄膜中定义的集成平面波导中。因此，该激光器件非常适合集成，例如集成到基于聚合物的芯片实验室微系统中。
