D2517922, May 8, 1979

Filed:

Aug 26, 1977

Appl. No.:

5/828252

Inventors:

Clifford L. Moody - San Jose CA
John M. Moody - San Jose CA

International Classification:

D1902

US Classification:

D19 91

US Patent:

20220385372, Dec 1, 2022

Filed:

Oct 20, 2021

Appl. No.:

17/505817

Inventors:

- Mountain View CA, US
Devin Brinkley - Redwood City CA, US
Paul Epp - Sunnyvale CA, US
John Moody - Belmont CA, US

International Classification:

H04B 10/50
H04B 10/548

Abstract:

A system includes a transmitter configured to output an optical signal. The transmitter includes a seed laser, an optical array including a plurality of array elements, and a plurality of phase shifters in a multi-layer arrangement. The multi-layer arrangement includes a plurality of layers between the seed laser and the optical array, wherein a first layer of the plurality of layers transmits light to a second layer of the plurality of layers. The first layer has fewer phase shifters than the second layer. The multi-layer arrangement also includes a plurality of branches wherein each branch includes a phase shifter from each of the plurality of layers connected in series between the seed laser and one of the plurality of array elements. Each phase shifter is configured to shift the optical signal incrementally to amass a total phase shift for each of the plurality of array elements.

International Classification:

H04B 10/112
H04B 10/50

Abstract:

A free-space optical communication system includes an optical phased array (OPA) photonic integrated chip, a transceiver photonic integrated chip, and one or more processors. The OPA chip includes a plurality of array elements and a plurality of phase shifters. The transceiver chip includes one or more transmitter components and one or more receiver components. The one or more processors are configured to transmit a first signal via the OPA chip and the transceiver chip, and receive a second signal via the OPA chip and the transceiver chip.

International Classification:

H04B 10/112
H04B 10/67

Abstract:

Aspects of the disclosure provide an optical communication system. The system may include a receiver lens system configured to receive a light beam from a remote optical communication system and direct the light beam to a photodetector. The system may also include the photodetector. The photodetector may be configured to convert the received light beam into an electrical signal, and the photodetector may be positioned at a focal plane of the receiver lens system. The system may also include a phase-aberrating element arranged with respect to the receiver lens system and the photodetector such that the phase-aberrating element is configured to provide uniform angular irradiance at the focal plane of the receiver lens system.
