Kevin Chen and his colleagues have demonstrated in a proof-of-concept experiment that they can contain light in such a way that makes it highly insensitive to defects that might be present in a material.

"From the perspective of photonic engineers, this is a wonderful learning opportunity to see the connections between lightwave engineering at length scale of micrometers, and quantum mechanics that typically deals with electron waves at length scale 10,000 times smaller," noted Kevin P. Chen.
