"overcomes tradeoff where larger switches handle higher speeds/ more data but use more energy/ large/ costly... 85 X 85 µm, fast 100 ps... tunes material's gain/ loss guiding optical signal towards right information highway exit... tame light flow on chip, enabling precise control over any light-based network’s connectivity... redirects in trillionths of second with minimal power consumption... silicon substrate, Indium Gallium Arsenide Phosphide semiconductor to manipulate IR... speeds up streaming movies, training AI"
