Publication number: 20210333818Abstract: Photonic processors are described. The photonic processors described herein are configured to perform matrix multiplications (e.g., matrix vector multiplications). Matrix multiplications are broken down in scalar multiplications and scalar additions. Some embodiments relate to devices for performing scalar additions in the optical domain. One optical adder, for example, includes an interferometer having a plurality of phase shifters and a coherent detector. Leveraging the high-speed characteristics of these optical adders, some processors are sufficiently fast to support clocks in the tens of gigahertz of frequency, which represent a significant improvement over conventional electronic processors.Type: ApplicationFiled: April 26, 2021Publication date: October 28, 2021Applicant: Lightmatter, Inc.Inventors: Nicholas C.

Patent number: 10935868Abstract: A light steeling system and method for diffractive steering of electromagnetic radiation such as visible light is disclosed. Embodiments of the light steering system include leaky-mode SAW modulators as light modulator devices. The SAW modulators preferably include reflective diffractive gratings. The gratings are mounted to/patterned upon an exit face that opposes an exit surface of the SAW modulator, in one example. Steering of light signals emitted from the SAW modulators in these systems can be accomplished by varying wavelength of light signals introduced to the SAW modulators, and/or by varying frequency of RF drive signals applied to the SAW modulators. In addition, light field generators that incorporate SAW modulators of the proposed light steering system within displays of the light field generators are also disclosed.Type: GrantFiled: September 25, 2018Date of Patent: March 2, 2021Assignee: The Charles Stark Draper Laboratory, Inc.Inventors: Steven J.

Publication number: 20190025666Abstract: A system and method for light field generation is disclosed. A proposed holographic display system encodes views of a scene into surface acoustic waves (SAW signals) that propagate along waveguides of SAW modulators and/or optical signals propagating in the waveguides. Each view provides a different perspective of the scene when the views are projected as light fields out of the SAW modulators and are viewed at different locations by an observer. In some examples, the system encodes the brightness information for each view into the light signals.Type: ApplicationFiled: July 20, 2018Publication date: January 24, 2019Inventors: Steven J.

Patent number: 10156770Abstract: Packaging and interconnect systems for edge-emitting light modulators are disclosed. Embodiments address the challenge of integrating many edge-emitting modulators such as surface acoustic wave (SAW) modulators together in a single light field generator system. In one example, a proposed light field generator system includes a stack of projector modules and a mounting block having slots. The projector modules preferably have a printed circuit board (PCB) form factor that enables the slots of the mounting block to receive and hold the modules. Each module includes a module board and one or more SAW substrates carried by the module board, and an array of SAW modulators are formed/fabricated within each substrate. Proposed substrate fabrication techniques provide wiring and routing of RF and optical signals to the SAW modulators within each substrate to achieve a density of light modulators suitable for practical application to light field projection systems.Type: GrantFiled: February 8, 2018Date of Patent: December 18, 2018Assignee: The Charles Stark Draper Laboratory, Inc.Inventors: Gregg E.
