Publication number: 20200049909Abstract: In some examples a silicon photonic (SiPh) solder reflowable assembly may comprise a silicon interposer bonded to an organic substrate, the silicon interposer having an optical grating disposed on the interposer to couple an optical signal, a lens array chip, the lens array comprising one or more lenses on a wafer, the lens array chip flip chip reflowed to the silicon interposer by a bonding agent and the one or more lenses having a predetermined shape that expands, collimates, and tilts a beam of the optical signal exiting the grating. The wafer has a coefficient of thermal expansion (CTE) that matches silicon and the one or more lenses and the grating are aligned in such a way the optical signal enters the grating at a desired angle.Type: ApplicationFiled: January 30, 2017Publication date: February 13, 2020Inventors: Sagi Mathai, Michael Rene Ty Tan, Marco Fiorentino, Paul Kessler Rosenberg, David Kielpinski, Wayne Victor Sorin

Patent number: 10461853Abstract: In example implementations, an optical gate is provided. The optical gate receives at least one optical signal via a waveguide of an optical memory gate. The optical gate compares a wavelength of the at least one optical signal to a resonant wavelength associated with a resonator. When the wavelength of the at least one optical signal matches the resonant wavelength, a value that is stored in the resonator is read out via the at least one optical signal. Then, the at least one optical signal with the value that is read out is transmitted out of the optical gate.Type: GrantFiled: December 5, 2018Date of Patent: October 29, 2019Assignee: Hewlett Packard Enterprise Development LPInventors: Nikolas A. Tezak, David Kielpinski, Jason Pelc, Thomas Van Vaerenbergh, Ranojoy Bose, Raymond G. Beausoleil

Patent number: 10367590Abstract: Examples described herein relate to concurrently performing operations on optical signals. In an example, a method includes providing, to an optical circuit, a first plurality of signals having a first optical property and encoding a first vector. A second plurality of signals is provided to the circuit that encodes a second vector and has a second optical property that is different from the first optical property. A first attribute-dependent operation is performed on the first plurality of signals via the circuit to perform a first matrix multiplication operation on the first vector, and concurrently, a second attribute-dependent operation is performed on the second plurality of signals to perform a second matrix multiplication operation on the second vector. The first matrix multiplication operation and the second matrix multiplication operation are different based on the first optical property being different from the second optical property.Type: GrantFiled: September 22, 2016Date of Patent: July 30, 2019Assignee: Hewlett Packard Enterprise Development LPInventors: David Kielpinski, Jason Pelc, Thomas Van Vaerenbergh, Nikolas Tezak, Gabriel Joe Mendoza, Raymond G.

Publication number: 20190170943Abstract: Examples described herein relate to an optical switching device wherein a racetrack resonant structure is positioned to determine a frequency passband by coupling. In some examples, a first waveguide receives an input light signal. A second waveguide is positioned to enable the input light signal to couple between the first waveguide and the second waveguide through a first coupling gap. The racetrack resonant structure is positioned adjacent to the first coupling gap to enable the input light signal to couple between one of the first waveguide and the second waveguide and the racetrack resonant structure through a second coupling gap. Thus, the racetrack resonant structure is to determine the frequency passband such that a first portion of the input light signal that coincides with the frequency passband is output by the first waveguide, and a second portion of the input light signal that does not coincide with the frequency passband is output by the second waveguide.Type: ApplicationFiled: December 5, 2017Publication date: June 6, 2019Inventors: David Kielpinski, Shuren Hu, Mir Ashkan Seyedi, Thomas Van Vaerenbergh, Gabriel Joel Mendoza, Jason Pelc

Patent number: 10256902Abstract: In example implementations, an apparatus includes a bus waveguide, a plurality of optical gates coupled to the bus waveguide and an injection coupler. The bus waveguide receives a plurality of constraint signals. Each optical gate outputs an internal state via a local phase shift when at least one of the plurality of constraint signals has a wavelength that matches a respective resonant wavelength. The injection coupler combines the at least one of the plurality of constraint signals with additional constraint signals that are injected. An error is detected in a bit of a message when an overall phase shift has occurred to the at least one of the plurality of constraint signals causing a power level to exceed a power level threshold of an optical gate when the at least one of the plurality of constraint signals constructively interferes with the additional constraint signals that are injected.Type: GrantFiled: November 13, 2015Date of Patent: April 9, 2019Assignee: Hewlett Packard Enterprise Development LPInventors: Nikolas Anton Tezak, David Kielpinski, Jason Pelc, Thomas Van Vaerenbergh, Ranojoy Bose, Raymond G.
