摘要： Modulation of a frequency of a transmitted optical wave includes: at least a first and second slopes for respective frequency sweeps associated with respective points in at least one of a first or second frame. A computed range and a computed velocity are determined based on combining first partial data derived from at least one measurement associated with a first backscattered portion of the transmitted optical wave with second partial data derived from at least one measurement associated with a second backscattered portion of the transmitted optical wave. The first backscattered portion is received during a frequency sweep at the first slope associated with a first point in the first frame. The second backscattered portion is received during a frequency sweep at the second slope associated with a second point in the first frame different from the first point or associated with at least one point in the second frame.

摘要： Light is provided to optical antennas (OAs) separated by a first set of spacings in a first OPA. Phases of light provided to respective OAs are controlled to form a transmitted beam whose angle is steered so that first and second lobes of a first angular intensity distribution (AID) scan over first and second portions of a region, respectively. Light is received from OAs separated by a second set of spacings in a second OPA into which light is received from directions associated with a second AID. The first lobe of the first AID and a first lobe of the second AID substantially overlap in angle during the scan of the first lobes, and the second lobe of the first AID and a second lobe of the second AID substantially overlap in angle during the scan of the second lobes.

摘要： A plurality of waveguide structures are formed in at least one silicon layer of a first member. The first member includes: a first surface of a first silicon dioxide layer that is attached to a second member that consists essentially of an optically transmissive material having a thermal conductivity less than about 50 W/(m·K), and a second surface of material that was deposited over at least some of the plurality of waveguide structures. An array of phase shifters is formed in one or more layers of the first member. An array of temperature controlling elements are in proximity to the array of phase shifters.

摘要： A method comprises: providing light to a plurality of optical antennas separated by a set of spacings in an optical phased array (OPA), wherein a plurality of phase shifters impose phase shifts onto light provided to respective optical antennas of the plurality of optical antennas; and managing the imposed phase shifts using a phase shift control module. The managing comprises a first mode of operation comprising: for a first subset of optical antennas within a distance from a center of the plurality of optical antennas, determining variations of imposed phase shifts smaller than a phase shift variation range, and for a second subset of optical antennas further than the distance from the center of the plurality of optical antennas, determining variations of imposed phase shifts larger than the phase shift variation range.

摘要： At least one beam of an optical wave is transmitted along a transmission angle toward a target location from a send aperture of a transmitter. The optical wave comprises at least a first portion, and a second portion having a different characteristic from a characteristic of the first portion. Two or more receivers include at least one receiver comprising: a receive aperture arranged in proximity to at least one of the send aperture or a receive aperture of a different receiver, an optical phased array within the receive aperture, the optical phased array being configured to receive at least a portion of a collected optical wave arriving at the receive aperture along a respective collection angle, and a filter configured to filter the received portion of the collected optical wave according to the characteristic of the first portion of the optical wave.

摘要： Aspects of the present disclosure describe systems, methods, and structures for aberration correction of optical phased arrays that employ a corrective optical path difference (OPD) in the near-field of an OPA to correct or cancel out aberrations in emitted beams of the OPA including those reaching far-field distances by generating a spatially-varying OPD across the aperture of the OPA that is substantially equal and opposite to an equivalent OPD of the aberration(s).
