Publication number: 20240079849Abstract: Disclosed is a coherent optical combining photonic integrated circuit that can detect and align light amplified by a scalable quantity of semiconductor optical amplifiers (SOAs). The light can be split into beams and amplified by individual SOAs in a PIC and combined via couplers in the PIC. The combined light can be measured using a photodetector and the light beams can be adjusted based the photodetector measurement to coherently combine the light to achieve high optical power from the photonic integrated circuit.Type: ApplicationFiled: September 2, 2022Publication date: March 7, 2024Inventors: John Parker, Tom Mader, Steven B.

Patent number: 9239439Abstract: Embodiments of the invention are directed to an optical USB (OUSB) to enhance the data rate of USB by adding super-high data rate (e.g. 10 Gbps) optical communication on top of its current specification so that backward compatibility is achievable. Mechanical tolerances may be achieved by using embedded lenses to expand a beam emerging from the connector prior to entering its mating connector and using an identical lens in the mating connector to collimate the beam back onto a fiber.Type: GrantFiled: October 29, 2013Date of Patent: January 19, 2016Assignee: Intel CorporationInventors: Jamyuen Ko, Hengju Cheng, Tom Mader

Patent number: 7412123Abstract: Briefly, in accordance with one or more embodiments, a backplane includes one or more optical links and is capable of receiving one or more circuit cards. Optical signals sent via the optical links may at least partially travel in a free space region between optical elements of the circuit cards and the optical links. Optical signals may also traverse the free space between optical links in the absence of a circuit card wherein the optical signal may travel to one or more other circuit cards on the backplane. As a result, in one or more embodiments a network between one or more of the circuit cards on the backplane may be automatically configured even in the absence of one or more circuit cards from the backplane.Type: GrantFiled: May 22, 2007Date of Patent: August 12, 2008Assignee: Intel CorporationInventors: Tom Mader, Christine Krause, Hengju Cheng, Jamyuen Ko
