In this Letter, we report a novel integrated additive and subtractive manufacturing (IASM) method to fabricate an information integrated glass module. After a certain number of glass layers are 3D printed and sintered by direct ${{\rm CO}_2}$CO laser irradiation, a microchannel will be fabricated on top of the printed glass by integrated picosecond laser, for intrinsic Fabry-Perot interferometer (IFPI) optical fiber sensor embedment. Then, the glass 3D printing process continues for the realization of bonding between optical fiber and printed glass. Temperature sensing up to 1000°C was demonstrated using the fabricated information integrated module. In addition, the long-term stability of the glass module at 1000°C was conducted. Enhanced sensor structure robustness and harsh temperature sensing capability make this glass module attractive for harsh environment structural health monitoring.
在本信函中，我们报告了一种新颖的集成增材与减材制造（IASM）方法，用于制造信息集成玻璃模块。在通过直接二氧化碳激光辐照对一定数量的玻璃层进行3D打印和烧结后，将通过集成皮秒激光在打印玻璃顶部制造一个微通道，用于嵌入本征法布里-珀罗干涉仪（IFPI）光纤传感器。然后，继续进行玻璃3D打印过程，以实现光纤与打印玻璃之间的键合。使用制造的信息集成模块展示了高达1000°C的温度传感。此外，还对玻璃模块在1000°C下的长期稳定性进行了测试。增强的传感器结构稳健性和苛刻温度传感能力使该玻璃模块对恶劣环境结构健康监测具有吸引力。
