A contrasting technique

Researchers at the Rochester Institute of Technology in New York have increased the switching contrast of a particular kind of all-optical flip-flop by 28 dB, resulting in a switching contrast of 36.6 dB. This could provide a huge leap in the performances of a range of photonic techniques, such as all-optical packet switching, all-optical label addressing, and square-wave clock generation, as well as other photonic devices housing semiconductor optical amplifiers or even passive nonlinear media.
