摘要： An optoelectronic device (20, 50) includes a planar substrate (30), an optical bus (40, 82, 84, 96, 140, 150, 180, 182, 224) disposed on the substrate and configured to convey coherent radiation through the bus, and an array (32, 72) of sensing cells (34, 74, 90, 160, 170, 200, 212, 380) disposed on the substrate. Each sensing cell includes at least one tap (92, 94, 144, 146, 226, 228) coupled to extract a portion of the coherent radiation propagating through the optical bus, an optical transducer (36, 108, 162, 172, 202, 204, 214) configured to couple optical radiation between the sensing cell and a target external to the substrate, and a receiver (114, 174, 178, 216, 218), which is coupled to mix the coherent radiation extracted by the tap with the optical radiation received by the optical transducer and to output an electrical signal responsively to the mixed radiation.

摘要： An optoelectronic apparatus includes a dual folding mirror, which is mounted on a carrier substrate and includes first and second reflecting surfaces disposed at opposite angles relative to a normal to the carrier substrate. First and second sensing devices are disposed respectively in proximity to the first and second reflecting surfaces. Each sensing device includes a planar substrate disposed on the carrier substrate and an array of sensing cells disposed on the planar substrate and including respective edge couplers disposed along the edge of the planar substrate so as to couple optical radiation between the sensing cells and the respective reflecting surface.

摘要： An optoelectronic device (28, 130) includes an array (32, 152) of optical transceiver cells (34, 90, 162) including respective optical transducers (36, 134, 164) configured to couple optical radiation between the transceiver cells and a target through respective optical apertures defined by the optical transducers. A tunable radiation source (22, 210, 240) outputs coherent radiation while tuning a wavelength of the coherent radiation over a selected range. An optical distribution network (38) conveys the coherent radiation from the radiation source to the optical transceiver cells for transmission via the optical transducers toward the target. Projection optics (44, 140, 154) project the optical apertures onto respective fields of view on the target, and include a dispersive element (148, 156), which shifts the fields of view across the target responsively to the tuning of the wavelength.
