Ultrafast laser inscription: an enabling technology for astrophotonics

Robert R. Thomson, Ajoy K. Kar, Jeremy Allington-Smith

摘要:

光子学在天文学中的应用在高度复用光谱学领域提供了重大优势,特别是当应用于超大望远镜时。这些包括近红外夜空光谱的抑制[J. Bland-Hawthorn等人,Opt. Express 12,5902(2004),S. G. Leon-Saval等人,Opt.Lett. 30,2545(2005)]和光谱仪的简化,使得它们可以集成到各个空间样本的光路中[J. Bland-Hawthorn等人,Proc SPIE 6269,62690 N(2006)]。有效地收集来自望远镜的光需要多模光纤和三维光子器件。我们提出了超快激光铭刻(ULI)[R. R. Thomson等人,Opt. Express 15,11691(2007)]作为制造用于天文光子应用的3D光子器件的最佳技术。

英文摘要:

The application of photonics to astronomy offers major advantages in the area of highly-multiplexed spectroscopy, especially when applied to extremely large telescopes. These include the suppression of the near-infrared night-sky spectrum [J. Bland-Hawthorn et al, Opt. Express 12, 5902 (2004), S. G. Leon-Saval et al, Opt. Lett. 30, 2545 (2005)] and the miniaturisation of spectrographs so that they may integrated into the light-path of individual spatial samples [J. Bland-Hawthorn et al, Proc SPIE 6269, 62690N (2006)]. Efficient collection of light from the telescope requires multimode optical fibres and three-dimensional photonic devices. We propose ultrafast laser inscription (ULI) [R. R. Thomson et al, Opt. Express 15, 11691 (2007)] as the best technology to fabricate 3D photonic devices for astrophotonic applications.
