Patent number: 11592558Abstract: Various technologies described herein pertain to a time of flight lidar sensor system that uses a coherent detection scheme. The lidar sensor system includes a laser source, a semiconductor optical amplifier, a combiner, and a balanced detector. The laser source emits an input optical signal. The semiconductor optical amplifier receives a first portion of the input optical signal and outputs a modulated optical signal (amplified and modulated). The combiner receives a second portion of the input optical signal and a returned optical signal received responsive to transmission of at least a portion of the modulated optical signal. The combiner coherently mixes the second portion of the input optical signal with the returned optical signal and outputs mixed optical signals. The balanced detector detects the mixed optical signals and generates an output signal (e.g., a differential photocurrent), which can be used to detect a distance to a target.Type: GrantFiled: May 18, 2020Date of Patent: February 28, 2023Assignee: GM CRUISE HOLDINGS LLCInventors: Abdelkrim El Amili, Jacob Levy, Scott Singer, Vala Fathipour, Ayan Chakrabarty, Kamel Benboudjema, Richard Kalantar Ohanian, David Lew, George Keseyan

Publication number: 20230036316Abstract: Various technologies described herein pertain to injection locking on-chip laser(s) and external on-chip resonator(s). A system includes a first integrated circuit chip and a second integrated circuit chip. The first integrated circuit chip and the second integrated circuit chip are separate integrated circuit chips and can be optically coupled to each other. The first integrated circuit chip includes a laser configured to emit light via a first path and a second path. The second integrated circuit chip includes a resonator formed of an electrooptic material. The resonator can receive the light emitted by the laser of the first integrated circuit chip via the first path and return feedback light to the laser of the first integrated circuit chip via the first path. The feedback light can cause injection locking of the laser to the resonator to control the light emitted by the laser (e.g., via the first and second paths).Type: ApplicationFiled: October 10, 2022Publication date: February 2, 2023Inventors: Jacob Levy, Ayan Chakrabarty, Vala Fathipour, Karim El Amili

Patent number: 11506842Abstract: An optical coupling device is described herein. The optical coupling device comprises a first waveguide and a second waveguide that are formed on a common substrate, and a resonator that is positioned out of plane with the two waveguides. The resonator and waveguides are positioned such that light traveling in each of the waveguides evanescently couples to the resonator but not to the other of the waveguides. The optical coupling device can be used in connection with improving linewidth of a laser source for a lidar sensor. In another example, the optical coupling device can be used in connection with wavelength division multiplexing.Type: GrantFiled: September 9, 2020Date of Patent: November 22, 2022Assignee: GM CRUISE HOLDINGS LLCInventors: Jacob Levy, Vala Fathipour, Lutfollah Maleki, Vladimir S.
