ALEXANDRIA, Va., Aug. 12 -- United States Patent no. 12,705,476, issued on Aug. 11, was assigned to Massachusetts Institute of Technology (Cambridge, Mass.).
"All-photonic artificial neural network processor via nonlinear optics" was invented by Jasvith Raj Basani (College Park, Md.), Mikkel Heuck (Somerville, Mass.), Dirk Robert Englund (Brookline, Mass.) and Stefan Ivanov Krastanov (Boston).
According to the abstract* released by the U.S. Patent & Trademark Office: "An all-photonic computational accelerator encodes information in the amplitudes of frequency modes stored in a ring resonator. Nonlinear optical processes enable interaction among these modes. Both the matrix multiplication and element-wise activation functions on these mode...
