According to recent research from the United States, "We demonstrate a nanoscale subpicosecond (ps) matamaterial device capable of terabit/second all-optical communication in the near-IR."
"The 600 fs response, 2 orders of magnitude faster than previously reported is achieved by accessing a previously unused regime of light-injection level, subpicosecond carrier dynamics In the alpha-Si dielectric layer of the metamaterial," wrote K.M. Dani and colleagues.
The researchers concluded: "Further, we utilize a previously unrecognized, higher-order, shorter-wavelength negative-index resonance in the fishnet structure, thereby extending device functionality ...
