Patent number: 11747446Abstract: According to various embodiments, a solid-state light detection and ranging (LiDAR) transmitter includes a tunable optical metasurface to selectively steer incident optical radiation long an azimuth axis. In some embodiments, different subsets of lasers in an array of lasers are activated to generate optical radiation for incidence on the metasurface at different angles of incidence on an elevation axis for unsteered deflection by the metasurface at corresponding angles of elevation. In some embodiments, a prism is positioned relative to the tunable optical metasurface to deflect the optical radiation from the optical assembly by the optical radiation source for incidence on the metasurface at an angle of incidence that is between the first steering angle and the second steering angle, such that the optical radiation incident on the metasurface and the steered output optical radiation from the metasurface spatially overlap within the prism.Type: GrantFiled: August 26, 2022Date of Patent: September 5, 2023Inventors: Ross D. Uthoff, Apurva Jain, Gleb M. Akselrod, Matthieu Saracco

Patent number: 10627993Abstract: A clipboard component provides a multi-item clipboard store. The clipboard component uses a technical strategy that facilitates its efficient adoption and use by end users and application developers. From an end user's standpoint, the clipboard component provides a new user experience which is easy for the users to discover, learn and use, due, in part, to the use of ergonomic control mechanisms for activating paste and copy operations. From a developer's standpoint, the clipboard component provides a way of allowing existing legacy applications to interact with a multi-item clipboard store, even though these applications were not originally created to provide that type of interaction. The clipboard component can also, upon instruction by a user, apply one or more supplemental operations to a copied content item, such as transferring the item to a target computing device.Type: GrantFiled: August 8, 2016Date of Patent: April 21, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Matthew Isaac Worley, Chaitanya Dev Sareen, Christopher Doan, Jason Morris Yore, Apurva Jain, Richard Fang

Publication number: 20130208754Abstract: A method for two-dimensional spatial (transverse) mode selection in waveguide and free-space laser resonators and associated laser systems employing said resonators. The invention is based on the cylindrical symmetry of the angular selectivity of reflecting volume Bragg gratings (R-VBGs) that are used as spectrally selective minors in resonators. Matching the divergence of a laser beam and the angular selectivity a reflecting volume Bragg grating can establish different losses for transverse modes of different orders, while not restricting the aperture of the laser resonator, and enables single mode operation for resonators that support a plurality of transverse modes. The invention provides a laser having increased brightness without a decrease of efficiency.Type: ApplicationFiled: February 10, 2012Publication date: August 15, 2013Applicants: OptiGrate Corp., University of Central Florida Research Foundation Inc.Inventors: Leonid Glebov, Apurva Jain, Vadim Smirnov, Christine Spiegelberg, George Venus
