  • Publication number: 20250076600
    Abstract: Embodiments of the present application disclose a photonic chip, a LiDAR, and a mobile device. The photonic chip has a substrate, a cladding layer, a first coupler, a first beam splitter, an emitting waveguide module, and a first optical adjusting monitoring module. The first beam splitter includes a first port, a second port, a third port, and a fourth port. The first beam splitter is configured to output the optical signal input through the first port through the third port and the fourth port, and to output the optical signal input through the third port through the first port and the second port. The first optical adjusting monitoring module includes a first photodetector. Monitors the optical power of the return light received by the emitting waveguide module through the first optical adjusting monitoring module integrated on the photonic chip, making the process more time-saving and labor-saving.

  • Patent number: 12196887
    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.
