Tiny chip optical booster makes light 100x stronger with almost no energy
A tiny optical booster built directly onto a chip is pointing toward a future where light, not just electricity, does the ...
Researchers at Tsinghua University developed the Optical Feature Extraction Engine (OFE2), an optical engine that processes data at 12.5 GHz using light rather than electricity. Its integrated ...
A tunable metasurface can control optical light in space and time, offering a path toward new ways of wirelessly and securely transmitting large amounts of data both on Earth and in space. It is a ...
In a paper published July 24 in the journal Nature Nanotechnology, a team of Caltech engineers reports building a metasurface patterned with miniscule tunable antennas capable of reflecting an ...
