Repeatability of LPG fixed exposure vs tracked

Spectra from a series of LPGs fabricated by two different methods. The first five were fabricated by exposing them to 40s of UV irradiation. The second five where exposed until the LP mode (LP14) of interested reached the corrected wavelength.<br>174um period LPG in PS750 fibre

本数据集包含通过两种不同制备工艺得到的一系列长周期光纤光栅（Long Period Gratings，LPG）的光谱数据。其中前五个样本采用40秒紫外（Ultraviolet，UV）辐照工艺制备；后五个样本则通过持续紫外辐照，直至目标LP模式（LP14）的波长达到校正后的指定值。本次刻制的光栅均为在PS750光纤上制备的、周期为174微米的长周期光纤光栅。
