Photonic capsules for injectable laser resonators
(PHYSorg.com Physics)

A KAIST research group presented photonic capsules for injectable laser resonators using microfluidic technology. The capsule`s diameter is comparable to a human hair and stable in gas and liquid media, so it is injectable into any target volume. The research group, headed by Professor Shin-Hyun Kim in the Department of Chemical and Biomolecular Engineering, applied an interesting optical property from nature.
