摘要： A first photonic die has a first coupling edge and a first die surface, and comprises: a first waveguide extending in proximity to the first coupling edge; a portion of the first die surface forming an alignment edge substantially parallel to the first waveguide; and a first alignment feature etched into or formed adjacent to the first coupling edge. A second photonic die has a second coupling edge and a second die surface, and comprises: a second waveguide extending in proximity to the second coupling edge; a portion of the second die surface configured to form a receptacle sized to constrain a position of the alignment edge; and a second alignment feature etched into or formed adjacent to the second coupling edge and configured to enable alignment with the first alignment feature when the first photonic die and the second photonic die are substantially aligned with each other.

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).

摘要： An apparatus comprises an optical cavity formed on a substrate and defining a round-trip optical path, an interface positioning at least a portion of a gain medium to provide an active portion of the round-trip optical path over which the gain medium provides sufficient gain for the optical wave to propagate around the round-trip optical path in a single mode, an output coupler coupling a portion of the optical wave out of the optical cavity from a passive portion of the round-trip optical path into a waveguide segment formed on the substrate, one or more tap couplers each diverting less than 50% of optical power from the waveguide segment, and one or more on-chip modules each receiving diverted optical power from at least one of the tap couplers and providing information associated with a laser that comprises the optical cavity and the gain medium.

摘要： Aspects of the present disclosure describe systems, methods, and structures—including LiDAR—that employ multiple detectors that may determine multiple incident angles of multiple received radiation beams and advantageously do not require or employ phase shifters in illustrative embodiments and may instead—employ optical Fourier transform structures.

摘要： Aspects of the present disclosure describe systems, methods, and structures for optical phased array calibration that advantageously may be performed as a single-pass measurement of phase offset with respect to only a single interference measurement. In sharp contrast to the prior art—systems, methods, and structures according to aspects of the present disclosure advantageously produce phase offsets and phase functions of each element without time-consuming iterative procedures or multiple detector signals as required by the prior art.
