Patent number: 11881435Abstract: A method for fabricating a three-dimensional (3D) static random-access memory (SRAM) architecture using catalyst influenced chemical etching (CICE). Utilizing CICE, semiconductor fins can be etched with no etch taper, smooth sidewalls and no maximum height limitation. CICE enables stacking of as many nanosheet layers a desired and also enables a 3D stacked architecture for SRAM cells. Furthermore, CICE can be used to etch silicon waveguides thereby creating waveguides with smooth sidewalls to improve transmission efficiency and, for photon-based quantum circuits, to eliminate charge fluctuations that may affect photon indistinguishability.Type: GrantFiled: May 3, 2022Date of Patent: January 23, 2024Assignee: Board of Regents, The University of Texas SystemInventors: Sidlgata V.

Publication number: 20230283520Abstract: The disclosed technology relates to intent driven network management. A system is configured to maintain an inventory store comprising records for a set of network entities in a network, wherein each network entity in the set of network entities is associated with a record in the inventory store. The system receives a user intent statement comprising an action and a flow filter representing network data flows on which the action is to be applied and queries, based on the flow filter, the inventory store to identify a plurality of network entities in the set of network entities to which the user intent statement applies. The system generates a plurality of network policies that implement the user intent statement based on the plurality of network entities and the action and enforces the plurality network policies.Type: ApplicationFiled: May 8, 2023Publication date: September 7, 2023Inventors: Rohit Prasad, Shashi Gandham, Hoang Nguyen, Abhishek Singh, Shih-Chun Chang, Navindra Yadav, Ali Parandehgheibi, Paul Mach, Rachita Agasthy, Ravi Prasad, Varun Malhotra, Michael Watts, Sunil Gupta

Publication number: 20230236471Abstract: Aspects of the present disclosure describe optical phased array structures and devices in which hyperbolic phase envelopes are employed to create focusing and diverging emissions in one and two dimensions. Tuning the phase fronts moves focal point spot in depth and across the array. Grating emitters are also used to emit light upward (out of plane). Adjusting the period of the gratings along the light propagation direction results in focusing the light emitted from the gratings. Changes in the operating wavelengths employed moves the focal spot along the emitters.Type: ApplicationFiled: March 8, 2023Publication date: July 27, 2023Applicant: Analog Photonics LLCInventors: Ehsan Hosseini, Michael Watts

Patent number: 11509116Abstract: An internal laser component of an optical device comprises: a waveguide that defines a guided mode of a first optical wave characterized by a first propagation constant associated with a first effective refractive index. An optical antenna grating comprises: a waveguide that defines a guided mode of a second optical wave characterized by a second propagation constant associated with a second effective refractive index, and a grating structure configured to emit a portion of the second optical wave in a selected direction.
