Storing Light In Chips
Roland Piquepaille writes "Recently, researchers have "stopped light" by storing light pulses in hot or extremely cold gases (check these former stories on Slashdot or at BBC News Online). Now, scientists from Stanford University have devised a method to store light pulses under ordinary conditions. In Light-storing chip charted, Technology Research News says this opens the way for all-optical communications switches, quantum computers and quantum communications devices. The researchers plan to demonstrate this technique by trapping microwave signals within a year. They think that a prototype which works at optical frequencies could be made in two to five years. This overview contains more details and references."
Then you would stare at a black screen. If all light is held and not transmitted, no waves are projected on your retina - or at least no ligthwaves from the screen.
You know it makes sense, a little reminder from jointm1k.
Well, no, because if light's held, you won't see it.
The image you see on the CRT is from the phosphors emitting light. If the elements of the screen held light, you would see a black image until the light was released.
