Patent number: 10976579Abstract: A liquid crystal waveguide (LCW) can include actively controlled incoupling of light into a LCW, such as by using a voltage-controlled electrode to actively vary a property of an LC material arranged to affect the incoupling of light into the LCW. Actively varying light incoupling into the LCW can be used, for example, such as for calibration or compensation or to provide closed-loop feedback such as to stabilize the amount of light into the LCW while accommodating or reducing sensitivity of the LCW to variations in one or more of: input laser light incidence angle, input laser wavelength, LCW or input laser temperature, input laser optical power level, or the like. This can advantageously help improve or maximize light incoupling efficiency, which can improve performance and robustness of the LCW under actual operating conditions. The LCW can be used for, among other things, beamsteering in in-plane and out-of-plane directions.Type: GrantFiled: August 9, 2018Date of Patent: April 13, 2021Assignee: Analog Devices, Inc.Inventors: Michael Ziemkiewicz, Scott Robert Davis, Scott D.

Patent number: 10684531Abstract: A light beam can be steered using a non-mechanical beam steerer structure. For example, a combination of sub-aperture and full-aperture beam steering structures can be used (e.g., corresponding to regions of controlled variation in an index of refraction). The sub-aperture elements can include tapered structures defining a saw-tooth or triangular footprint in the plane in which the in-plane steering is performed. Respective rows of sub-aperture tapered structures can be configured to controllably steer the light beam in the first in-plane direction, wherein at least one row of sub-aperture tapered structures defines a first base region edge that is tipped at a first specified in-plane angle relative to a second base region edge defined by another row. Use of the tipped configuration can simplify a configuration of the beam steerer structure, such as allowing a configuration lacking a compensation plate at the input.Type: GrantFiled: February 22, 2019Date of Patent: June 16, 2020Assignee: Analog Devices, Inc.Inventors: Michael Ziemkiewicz, Tyler Adam Dunn, Michael Howard Anderson, Scott Robert Davis

Publication number: 20200019037Abstract: An electro-optical beamsteerer can be coupled with other optical structures. For example, such optical structures can be used to shape a beam being steered by the beamsteerer or shape a field-of-regard (FOR) addressable from the perspective of the beamsteerer. Optical elements placed at an output of the LCW can be used as a “spot mapper” to increase or decrease the field of view that can be scanned by a beam steered by the LCW, as an illustrative example, Lenses or other optical elements can also be used to correct distortion in the steered beam distribution across the field of view, such as to provide a “smile corrector.” In a similar manner, optical elements can be placed at an input to the beamsteerer, such as to provide a beam expander to change the size of the beam profile inside the beamsteerer device.Type: ApplicationFiled: June 21, 2019Publication date: January 16, 2020Inventors: Michael Ziemkiewicz, Scott Robert Davis, Joseph D.

Patent number: 10120261Abstract: The present subject matter includes apparatus and techniques that can be used to reduce losses in systems that perform steering of a light beam. Such steering can be performed in a non-mechanical manner, such as using an electrically-controlled optical structure (e.g., an electro-optical structure). For example, a waveguide can be used to adjust an angle of a light beam (e.g., steer the light beam). The waveguide can include a core, a cladding including an electro-optic material, and electrodes defining an arrangement that, when selectively energized, adjusts an index of refraction of the electro-optic material. In particular, electrode arrangements as described herein can be used to reduce losses, such as losses that would occur due to diffraction.Type: GrantFiled: April 5, 2017Date of Patent: November 6, 2018Assignee: Analog Devices, Inc.Inventors: Michael Ziemkiewicz, Scott Robert Davis, Michael Howard Anderson, Tyler Adam Dunn

Patent number: 8825865Abstract: A system and methodology for network planning in which a software based tool provides network engineers with the capability to more precisely plan for traffic loading within the network on a cell site by cell site basis. Thus for each cell site, variations in geographic location, device mix, historical usage patterns and other factors are taken into account to allow for more accurate network planning and for more efficient use of capital. Cell sites with a higher traffic profile based upon historic device mix and usage patterns will be associated with lower OSF values thus enhancing the user experience for a device user in communication with that cell site. On the other hand, for cell sites with a lesser traffic profile, a higher OSF value is ascribed thus allowing for capital to be deployed elsewhere while still maintaining a positive user experience for users relying on that cell site.Type: GrantFiled: April 5, 2012Date of Patent: September 2, 2014Assignee: Clearwire IP Holdings LLCInventors: Howard Anderson, Hemanth Pawar, Hetal Mistry
