Patent number: 11914415Abstract: An optical neural network is constructed based on photonic integrated circuits to perform neuromorphic computing. In the optical neural network, matrix multiplication is implemented using one or more optical interference units, which can apply an arbitrary weighting matrix multiplication to an array of input optical signals. Nonlinear activation is realized by an optical nonlinearity unit, which can be based on nonlinear optical effects, such as saturable absorption. These calculations are implemented optically, thereby resulting in high calculation speeds and low power consumption in the optical neural network.Type: GrantFiled: May 4, 2022Date of Patent: February 27, 2024Assignee: Massachusetts Institute of TechnologyInventors: Jacques Johannes Carolan, Mihika Prabhu, Scott A.

Patent number: 11685270Abstract: Disclosed is an apparatus for use in wireless energy transfer, which includes a first resonator structure configured to transfer energy non-radiatively with a second resonator structure over a distance greater than a characteristic size of the second resonator structure. The non-radiative energy transfer is mediated by a coupling of a resonant field evanescent tail of the first resonator structure and a resonant field evanescent tail of the second resonator structure.Type: GrantFiled: September 1, 2020Date of Patent: June 27, 2023Assignee: MITInventors: Aristeidis Karalis, Andre B.

Patent number: 11579363Abstract: An integrated optical beam steering device includes a planar Luneburg lens that collimates beams from different inputs in different directions within the lens plane. It also includes a curved (e.g., semi-circular or arced) grating coupler that diffracts the collimated beams out of the lens plane. The beams can be steered in the plane by controlling the direction along which the lens is illuminated and out of the plane by varying the beam wavelength. Unlike other beam steering devices, this device can operate over an extremely wide field of view—up to 180°—without any aberrations off boresight. In other words, the beam quality is uniform in all directions, unlike with aplanatic lenses, thanks to the circular symmetry of the planar Luneburg lens, which may be composed of subwavelength features. The lens is also robust to misalignment and fabrication imperfections and can be made using standard CMOS processes.Type: GrantFiled: October 8, 2021Date of Patent: February 14, 2023Assignee: Massachusetts Institute of TechnologyInventors: Josue Lopez, Samuel Kim, Jamison Sloan, Boris Kharas, Jeffrey Scott Herd, Marin Soljacic, Cheryl Marie Sorace-Agaskar, Suraj Deepak Bramhavar, Steven Glenn Johnson, George Barbastathis

Publication number: 20220043323Abstract: An integrated optical beam steering device includes a planar dielectric lens that collimates beams from different inputs in different directions within the lens plane. It also includes an output coupler, such as a grating or photonic crystal, that guides the collimated beams in different directions out of the lens plane. A switch matrix controls which input port is illuminated and hence the in-plane propagation direction of the collimated beam. And a tunable light source changes the wavelength to control the angle at which the collimated beam leaves the plane of the substrate. The device is very efficient, in part because the input port (and thus in-plane propagation direction) can be changed by actuating only log2 N of the N switches in the switch matrix. It can also be much simpler, smaller, and cheaper because it needs fewer control lines than a conventional optical phased array with the same resolution.Type: ApplicationFiled: October 15, 2021Publication date: February 10, 2022Applicant: Massachusetts Institute of TechnologyInventors: Scott A.

Publication number: 20220012619Abstract: A photonic parallel network can be used to sample combinatorially hard distributions of Ising problems. The photonic parallel network, also called a photonic processor, finds the ground state of a general Ising problem and can probe critical behaviors of universality classes and their critical exponents. In addition to the attractive features of photonic networks—passivity, parallelization, high-speed and low-power—the photonic processor exploits dynamic noise that occurs during the detection process to find ground states more efficiently.Type: ApplicationFiled: April 26, 2021Publication date: January 13, 2022Applicant: Massachusetts Institute of TechnologyInventors: Charles ROQUES-CARMES, Yichen Shen, Li JING, Tena DUBCEK, Scott A.
