提出了一种改进的小光斑直接紫外写入方案,以解决切趾引起的相移。数值和分析模拟的计划证明与修改后的技术制作的光栅的实验结果。
A modification to the small-spot direct UV writing scheme is presented to resolve apodization-induced phase shift. Numerical and analytic simulations of the scheme are demonstrated alongside experimental results of gratings fabricated with the modified technique.
