The ongoing commercialisation of the space sector is creating numerous opportunities for photonics technologies, Matthew Dale learns
With numerical apertures of 0.10 to 0.30 and core diameters available from 50 to 2,000µm, the new fibres are ideal for applications ranging from spectroscopy to sensing
Figure 1: The slow optical cooking setup: A silica microfibre filled with deionised water is coupled to two microfibers, MF1 and MF2, which are oriented perpendicular to the microfibre and connected to an optical spectrum analyser and broadband light source. The heating effect caused by the broadband WGMs is illustrated in red.

Illustration of a three-dimensional crystal with various types of confining centres. (a) Crystal with four confining centres, each trapping waves (yellow) in all three dimensions simultaneously. (b) Crystal with a linear confining centre where waves can propagate in one dimension, analogous to an optical fibre. (c) Crystal with a planar confining centre where waves can propagate in two dimensions, analogous to a 2D electron gas. (Image: Vos et al.)
