Abstract: A light detection and ranging (LIDAR) system for a vehicle can include: a light source configured to output a transmit beam at a first orientation; a reflective surface configured to redirect the transmit beam from the first orientation to a second orientation; and a lens interface configured to receive the transmit beam at the first orientation and focus the transmit beam onto the reflective surface; wherein the LIDAR system emits the transmit beam at the second orientation into an environment of the LIDAR system.

Abstract: A LIDAR device for a vehicle includes an integrated chip. The integrated chip includes a substrate layer, a cladding layer, a waveguide, a scattering array, and a reflector layer. The cladding layer is disposed on the substrate layer to form an interface with the substrate layer. The waveguide is disposed within the cladding layer and configured to route an infrared optical field. The scattering array is disposed within the cladding layer between the waveguide and the interface and perturbs the infrared optical field and scatters the infrared optical field into a first beam propagating toward a surface of the cladding layer and into a second beam propagating towards the interface. The reflector layer is disposed within the cladding layer between the waveguide and the surface of the cladding layer to reflect the first beam towards the interface.

Abstract: A LIDAR system includes a substrate and an emitter coupled to the substrate and configured to emit a light beam along a first axis of the substrate. The LIDAR system includes an optic device coupled to the substrate and configured to split the light beam into a plurality of light beams. The LIDAR system includes an optical amplifier array coupled to the substrate and configured to amplify the plurality of light beams received from the optic device to generate a plurality of amplified light beams. The LIDAR system includes a transceiver coupled to the substrate and configured to redirect the plurality of amplified light beams from traveling along the first axis of the substrate to traveling along a second axis of the substrate that is different from the first axis.

Abstract: A LIDAR transceiver includes a source input, coherent cells, and an optical switch. The optical switch is configured to switchably couple the source input to the coherent cells. At least one of the coherent cells includes an input port, an optical antenna, and a splitter. The input port is coupled to the optical switch and the splitter is coupled between the input port and the optical antenna. The splitter is configured to split a received portion of a laser signal into a local oscillator signal and a transmit signal, where the transmit signal is emitted through the optical antenna. A reflection of the transmit signal is received through the optical antenna as a reflected signal, where the splitter is further configured to output a return signal that is a portion of the reflected signal.

Abstract: A light detection and ranging (LIDAR) sensor system mounted to a vehicle includes a first device and a second device coupled to the first device. The first device includes a laser source and one or more optical components. The first device is configured to output an optical signal associated with a local oscillator (LO) signal. The second device includes an optical amplifier array device and a transceiver device. The optical amplifier array device includes an integrated optical component and is configured to amplify the optical signal. The transceiver device is configured to transmit the amplified optical signal to an environment and receive a returned optical signal that is reflected from an object in the environment.

Abstract: A structure of a silicon photonics device for LIDAR includes a first insulating structure and a second insulating structure disposed above one or more etched silicon structures overlying a substrate member. A metal layer is disposed above the first insulating structure without a prior deposition of a diffusion barrier and adhesion layer. A thin insulating structure is disposed above the second insulating structure. A first configuration of the metal layer, the first insulating structure and the one or more etched silicon structures forms a free-space coupler. A second configuration of the thin insulating structure above the second insulating structure forms an edge coupler.
