AI 中文摘要
我们展示了一组使用双光子聚合制造的超紧凑型光谱仪，每个长度不到1毫米，直接打印在光纤上。这种完全集成、无需对准的架构能够实现极低质量的仪器，在天体光子学、空间系统、无人机传感和量子光学等领域具有广泛潜力。介绍了两种透射配置，它们在针对J和H波段操作优化的单片印刷结构中结合了光束扩展光学元件、色散元件和杂散光抑制。粗光栅提供约R = 30的分辨率。实验表征证实了光纤耦合、完全印刷光谱仪的可行性，并证明了它们作为下一代集成光子仪器可部署组件的前景。
英文摘要
We present a set of ultra-compact spectrographs fabricated using two-photon polymerisation, each under 1 mm in length and printed directly onto an optical fiber. This fully integrated, alignment-free architecture enables extremely low-mass instrumentation with broad potential across astrophotonics, space systems, drone-based sensing, and quantum optics. Two transmissive configurations are presented; they combine beam-expansion optics, dispersive elements, and stray-light suppression within monolithic printed structures optimised for J- and H-band operation. Coarse gratings provide resolving powers of approximately R = 30. Experimental characterisation confirms the feasibility of fiber-coupled, fully printed spectrographs and demonstrates their promise as deployable components for next-generation integrated photonic instrumentation.
