摘要： Aspects of the present disclosure describe large scale steerable optical switched arrays that may be fabricated on a common substrate including many thousands or more emitters that may be arranged in a curved pattern at the focal plane of a lens thereby allowing the directional control of emitted light and selective reception of reflected light suitable for use in imaging, ranging, and sensing applications including accident avoidance.

摘要： An optical phase shifter may include a waveguide core that has a top surface, and a semiconductor contact that is laterally displaced relative to the waveguide core and is electrically connected to the waveguide core. A top surface of the semiconductor contact is above the top surface of the waveguide core. The waveguide core may include a p-type core region and an n-type core region. A p-type semiconductor region may be in physical contact with the n-type core region of the waveguide core, and an n-type semiconductor region may be in physical contact with the p-type core region of the waveguide core. A phase shifter region and a light-emitting region may be disposed at different depth levels, and the light-emitting region may emit light from a phase shifter region that is in a position adjacent to the light-emitting region.

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. A collected optical wave is received at receive apertures of two or more receivers. Each receiver comprises: 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, which receives at least a portion of a collected optical wave arriving at the receive aperture along a respective collection angle, and a detector that provides a signal based on the received portion of the collected optical wave. An estimated distance associated with the collected optical wave is determined based on a combination that includes a respective component corresponding to each of two or more of the signals provided from the detectors of the two or more receivers.

摘要： An apparatus includes: an optical phased array (e.g., on a photonic integrated circuit), a focusing element, which can be at a fixed position relative to the optical phased array and configured to receive an optical beam from the optical phased array, and a steering element, which can be at a fixed position relative to the focusing element and configured to transmit the optical beam received from the focusing element. In some implementations, at least one of the focusing element or the steering element is externally coupled to the photonic integrated circuit.

摘要： An apparatus comprises: a first integrated circuit comprising: a plurality of sets of optical waveguides, each set of optical waveguides including a plurality of optical waveguide segments, and a plurality of optical emitter elements arranged over a first surface of the first integrated circuit, each optical emitter element coupled to a distal end of one of the optical waveguide segments; and a second integrated circuit comprising: a plurality of optical phase shifters that each provide a phase-shifted optical wave that is coupled to the first integrated circuit from a first edge surface of the second integrated circuit. The first edge surface of the second integrated circuit is in proximity to a row of proximal ends of the optical waveguide segments of a first set of the plurality of sets of optical waveguides.

摘要： Aspects of the present disclosure describe optical phased array structures and devices in which hyperbolic phase envelopes are employed to create focusing and diverging emissions in one and two dimensions. Tuning the phase fronts moves focal point spot in depth and across the array. Grating emitters are also used to emit light upward (out of plane). Adjusting the period of the gratings along the light propagation direction results in focusing the light emitted from the gratings. Changes in the operating wavelengths employed moves the focal spot along the emitters.

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).
