Laser communications often take the lion’s share of attention when it comes to the use of photonics in space, but lasers will also play a vital role locating resources on the Moon and other objects in the solar system, according to NASA’s Berhanu Bulcha.
‘The next big thing in my area is developing an integrated photonics device-based THz spectrometer. NASA has a great interest in developing sensitive and small SWaP (size, weight and power) instruments for space missions,’ he said.

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.)
