#Bragg gratings and #Brillouin lasers.
https://optics.org/news/16/12/6
Have been put to work by a team at #Sydney Uni to do some very useful stuff (I s'pose) with #Pure #Laser #Light

... the Bragg gratings are reconfigurable: they can be written, erased and re-tuned after creation using only laser light, without needing to refabricate the device. This allows chip-scale lasers to be programmed on demand for low-noise single-mode or cascaded multi-mode operation.
...It’s a general framework for controlling optical processes on photonic chips.”
... photonic chips, should lead us to cleaner sources of quantum light and frequency comb lasers. These have emerging applications in communications and advanced navigation technology such as GPS.

Virtually Imaged Phased Arrays (#VIPAs) are contributing to #Brillouin #microscopy, enabling a deeper understanding of biological tissue mechanics. Brillouin microscopy analyzes the inelastic #scattering of light, offering insights into mechanical properties. VIPAs play a crucial role in the #spectrometers used for this technique, helping to precisely measure the subtle frequency shifts that occur.
