本文介绍了一种基于微光纤环路谐振器的可调谐高精细度微滤波器。微光纤环路的长度可以通过一个小的圆柱形压电陶瓷来控制。根据我们的计算，该谐振器的最大Q因子为2400，灵巧度为4.3。结果表明，MLR滤波器的最大消光比约为10 dB，自由频谱范围变化范围可大于100 GHz。由于微纤维的曲率半径更大，该装置也可以集成到更小的尺寸中。(C) 2008年美国物理研究所。
In this paper, a tunable high finesse microfilter is described, which is based on microfiber loop resonator (MLR). The length of microfiber loop could be controlled by a small cylindrical piezoelectric ceramic. As we calculated, this resonator has the maximum Q factor of 2400 and the finesse of 4.3. MLR filter was demonstrated that the maximum extinction ratio is about 10 dB, and the free spectral range variation range could be more than 100 GHz. This device could also be integrated into a smaller size due to the bigger radius of curvature of the microfiber. (C) 2008 American Institute of Physics.
