"Claims of "unexpected and stunning new physical phenomena" are rare in the abstract of a reputable scientific paper. But the latest report by photonics crystal pioneer John Joannopoulos and his group at MIT, soon to be published in Physical Review Letters, does not disappoint."
Some more excerpts from the article:
"The researchers document the ultimate control over light: a way to shift the frequency of light beams to any desired colour, with near 100 per cent efficiency...
If the effect can be harnessed, it will revolutionise a range of fields turning heat into light, for example, or prized terahertz rays. Right now, the only way to shift the frequency of a light beam involves sending an extremely intense light pulse with a power of many megawatts or even gigawatts along next to it..."
