    摘要： An apparatus comprises a photonic integrated circuit comprising a first optical coupler coupled to an optical source and a second optical coupler coupled to one or more photonic circuit elements integrated in the photonic integrated circuit; and a non-reciprocal optical element optically coupled to the first optical coupler and the second optical coupler. At least one of the first optical coupler or the second optical coupler is configured as a polarization-sensitive optical antenna that has an angular radiation function comprising at least (1) a peak intensity of a transverse magnetic optical field associated with a first angular direction, and (2) a peak intensity of a transverse electric optical field associated with a second angular direction different from the first angular direction.

    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： 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.
