Patent number: 11586094Abstract: Improved architectures and related methods for enhancing entangled photon generation in optical systems are described. Photons from a light source are coupled from the fundamental mode into an optical resonator in a higher-order mode. The optical resonator comprises a photon generation portion configured to generate entangled photons from the coupled photons. The entangled photons are selectively extracted from the optical resonator in the fundamental mode while the remaining photons propagate through the optical resonator mode and combine with the source photons entering the optical resonator. While the source photons propagating or entering the optical resonator resonate within the optical resonator, the entangled photons are not resonant with the optical resonator, and are selectively extracted before traversing a complete cycle in the optical resonator. Extracted entangled photons can then be output for use in, for example, a communication system.Type: GrantFiled: July 13, 2021Date of Patent: February 21, 2023Assignee: Honeywell International Inc.Inventors: Chad Fertig, Matthew Wade Puckett, Matthew Robbins, Neil A.

Patent number: 11536908Abstract: A multilayer waveguide coupler comprising a first grating and a second grating is provided. Each first copropagating waveguide of the first grating has a first periodically modulated width. Each second copropagating waveguide of the second grating has a second periodically modulated width. The second grating is positioned so that a phase offset is present between the first periodically modulated width of the first copropagating waveguides and the second periodically modulated width of the second copropagating waveguides. The grating spaced distance and phase offset are selected so that light diffracted out of the first copropagating waveguides and the second copropagating waveguides in the first direction interferes constructively to form the first light beam and light diffracted out of the first copropagating waveguides and the second copropagating waveguides in the second direction interferes destructively.Type: GrantFiled: May 4, 2021Date of Patent: December 27, 2022Assignee: Honeywell International Inc.Inventors: Matthew Wade Puckett, Chad Fertig, Neil A.

Patent number: 11442148Abstract: A sensor system comprises a pulsed light source, and a passive sensor head chip in communication with the light source. The sensor head chip includes a first photonics substrate, a transmitting optical component on the first photonics substrate and configured to couple a pulse, transmitted through a first optical fiber from the light source, into a region of interest; and a receiving optical component on the first photonics substrate and configured to couple backscattered light, received from the region of interest, into a second optical fiber. A signal processing chip communicates with the sensor head chip and light source. The signal processing chip includes a second photonics substrate and comprises a passive optical filter array that receives the backscattered light from the second optical fiber. The filter array includes notch filters in communication with each other and operative for frequency selection; and optical detectors respectively coupled to the notch filters.Type: GrantFiled: September 12, 2019Date of Patent: September 13, 2022Assignee: Honeywell International Inc.Inventors: Steven Tin, Chad Fertig, Matthew Wade Puckett, Neil A.

Patent number: 11408912Abstract: An optomechanical device for producing and detecting optical signals comprising a proof mass assembly, one or more laser devices, and a circuit. The one or more laser devices are configured to generate a first optical signal and a second optical signal. The circuit is configured to modulate, with an electro-optic modulator (EOM), the second optical signal, output the first optical signal and the second optical signal to the proof mass assembly, generate a filtered optical signal corresponding to a response by the proof mass assembly to the first optical signal without the second optical signal, and generate an electrical signal based on the filtered optical signal, wherein the EOM modulates the second optical signal based on the electrical signal.Type: GrantFiled: August 13, 2019Date of Patent: August 9, 2022Assignee: Honeywell International Inc.Inventors: Joshua Dorr, Chad Fertig, Arthur Savchenko, Steven Tin, Neil Krueger

Patent number: 10393618Abstract: Methods and apparatuses are provided for evaluating or testing stiction in Microelectromechanical Systems (MEMS) devices utilizing a mechanized shock pulse generation approach. In one embodiment, the method includes the step or process of loading a MEMS device, such as a multi-axis MEMS accelerometer, into a socket provided on a Device-Under-Test (DUT) board. After loading the MEMS device into the socket, a series of controlled shock pulses is generated and transmitted through the MEMS device utilizing a mechanized test apparatus. The mechanized test apparatus may, for example, repeatedly move the DUT board over a predefined motion path to generate the controlled shock pulses. In certain cases, transverse vibrations may also be directed through the tested MEMS device in conjunction with the shock pulses. An output of the MEMS device is then monitored to determine whether stiction of the MEMS device occurs during each of the series of controlled shock pulses.Type: GrantFiled: June 22, 2016Date of Patent: August 27, 2019Assignee: NXP USA, Inc.Inventors: Peter T.
