a new, extremely tiny light guide is designed quite differently. Instead of holding the light in, this nanoscale fiber lets about half its light energy flow outside in a glowing, evanescent field. It acts "like a rail for the light," said Eric Mazur, a professor of physics at Harvard University who led the research team that developed what are called optical nanowires.
