Fibre Bragg Gratings

 * The background in the range 0.9–1.8µm is predominantly from the de-excitation of atmospheric hydroxyl (OH) molecules at an altitude of≈90 km (Meinel 1950; Dufay 1951) [arXiv:1212.1201]
 * OH suppression using aperiodic ﬁbre Bragg gratings (Bland-Hawthorn et al. 2004; 2008; 2011)
