Optical Ring Resonator

Famous quotes containing the words optical and/or ring:

“It is said that a carpenter building a summer hotel here ... declared that one very clear day he picked out a ship coming into Portland Harbor and could distinctly see that its cargo was West Indian rum. A county historian avers that it was probably an optical delusion, the result of looking so often through a glass in common use in those days.”

Like a great ring of pure and endless light,”
