| description | A wavelength converter for LiDAR systems, such as automotive LiDAR, is disclosed. Implementation of the wavelength converter in LiDAR systems makes possible generation and modulation of laser light in the silicon response region, conversion of the laser light to an eye-safe wavelength for emission and reflection from a target, and efficient conversion of the wavelength of the laser light to the silicon response region. The wavelength converter may implement a single-loop counter-propagating wavelength conversion scheme which provides both up-conversion and down-conversion of the signal within the same loop. The wavelength conversion design also has the potential for vehicle-to-vehicle (V2V) communication to enable a combined LiDAR and V2V communication system. |
