    Abstract: A silicon photonic chip, a LiDAR, and a mobile device are disclosed. The silicon photonic chip includes a cladding, a transceiving waveguide module, a first photoelectric detection module, and a first polarization rotator. An emitting waveguide of the transceiving waveguide module extends along a first direction and is configured to transmit and emit a detection light, and the first receiving waveguide of the transceiving waveguide module is arranged at intervals along a second direction from the emitting waveguide and is configured to receive and transmit an echo light. The first photoelectric detection module is configured to receive a first local oscillator light and the echo light output by the first receiving waveguide. The first polarization rotator is disposed upstream of the first photoelectric detection module.

    Abstract: The present embodiment discloses a photonic chip module, LiDAR, and a mobile device. The photonic chip module includes a photonic chip and a reflection unit. The photonic chip includes a cladding and multiple first transceiving waveguide modules. The first transceiving waveguide module is embedded in the cladding, and the first emergent end and the first incident end are arranged at intervals along a first preset direction, collectively forming the first transceiving end of each first transceiving waveguide module, with these ends being spaced along a second preset direction. The reflection unit includes multiple reflection modules arranged along the second preset direction. Each reflection module has a first reflection surface. The photonic chip module provided in this embodiment is advantageous for increasing the detection field of view of the LiDAR under the same resolution conditions.

    Abstract: Embodiments of the present application disclose a photonic chip module, a LiDAR and a movable device. The photonic chip module includes a photonic chip and a reflection module. The photonic chip includes a plurality of transceiving waveguide modules. A plurality of accommodating grooves are provided on a first surface of the photonic chip. The reflection module has a plurality of reflecting surfaces, and each reflecting surface is arranged at intervals along the second preset direction. The reflection surface is used to reflect the detection light so that the detection light is emitted in a direction that is not perpendicular to the thickness direction. The photonic chip module is conducive to improving the detection field of view of the LiDAR under the condition of the same resolution, or improving the resolution under the condition of the same total detection field of view.
