This cloaking device will compress the light passing through the optical cable by means of a special silicon lens, causing some light to speed up, while other light that passes through it is slowed down. A different lens that is located a little farther up the cable will put the light back together, which means the emerging light looks unaltered, but there was some space in between in reality earlier on.
This sounds like a good way to implement secure communications – imagine embedding your messages in strategic areas of a time lag. We do look forward to see how such technology is going to change the way we live in the future. How about you? [research paper abstract]
