查询词典 prevent

In the thesis, we use R-Soft program to find the appropriate photonic crystal structure which can replace laser cleaved mirror and provide high reflectivity as high as 71% for 980 nm laser. Furthermore, we replace mirror with air bridge mirror in order to prevent light from escaping below photonic crystal. Then we observe whether it can provide higher reflectivity.
