提出了一种非对称分布布拉格反射器（DBR）波长可调谐塑料激光器。该器件由一对长周期波导光栅和一个掺杂有机染料的聚合物有源波导组成。由于两个DBR之间的光栅周期的差异，可以根据反射波长之间的谐振的游标效应来调谐激射波长。利用该原理操作的塑料激光器装置具有作为紧凑且可广泛调谐的光源的前景，因为可以预期有机发光材料的宽发射带中的大波长偏移具有有效折射率的小变化。
A wavelength tunable plastic laser with asymmetric distributed Bragg reflectors (DBRs) is proposed. This device consists of a pair of long-period waveguide gratings and a polymeric active waveguide doped with an organic dye. Due to the difference in grating periods between the two DBRs, the lasing wavelength can be tuned in accordance with a Vernier effect of the resonance between the reflection wavelengths. The plastic laser device operated with this principle has promise as a compact and widely tunable light source because a large wavelength shift in a wide emission band of an organic luminescent material can be expected with a small variation in the effective index.
