Illuminating the space junk problem

Benjamin Skuse explores photonics-based efforts to track, and possibly even remove, debris from the very crowded region of near-Earth space

Sydney Institute for Astronomy researchers have developed a new type of wavefront sensor that leverages a ‘photonic lantern’ and deep learning. (Norris et al.)

Lighting the way for astronomy

Researchers have developed a wavefront sensor using a ‘photonic lantern’ that could optimise humanity’s viewing of the cosmos

Biological imaging reaches new depths

Shaping light wavefronts is improving many areas of microscopy – and is enabling Nobel Prize winner Eric Betzig’s most important work yet, finds Andy Extance

Final frontier

Rachel Berkowitz looks at the photonics technology being developed for probing the universe, which in turn is leading to better commercial products
