| 摘 要： | 介绍了相位掩膜特性对光纤光栅 (OFG)性能的影响。理论分析和实验均表明 ,相位掩膜版的性能直接影响到啁啾光纤光栅功率谱的平坦度以及时延波动的大小 ,由于时延波动是影响啁啾光栅色散补偿的一个重要因素 ,因此对掩膜版的性能要求必须十分严格。通过掩膜版的选择以及紫外扫描曝光过程的控制 ,制作出了高质量的啁啾光纤光栅 ,时延波动小于 2 0 ps,功率波动小于 1dB

| Abstract: | In this article the influence of phase mask characteristic on OFG performance is introduced. The theory analysis and experiments show that the characteristic of the phase mask directly influence the power flatten coefficient and the time delay deviation (TDD) of the chirped OFG, then the TDD will influence dispersion effect of chirped OFG, so the parameters of the phase mask must be stricted. By choosing good quality phase mask and controlling the UV scan exposal course, the high quality OFG is fabricated which has the time delay deviation less than 20 ps and its reflectivity is flatness with ripple coefficient less than 1 dB. |
