  • Publication number: 20250030218
    Abstract: The present application provides an optical device and a method of fabricating the same. The optical device include a semiconductor stack structure, an anti-reflective film and a highly-reflective film. The semiconductor stack structure is configured to generate a laser beam and emit the laser beam from its front facet while receiving an electric current. The anti-reflective film is disposed on the front facet of the semiconductor stack structure and configured to increase the transmittance (reduce a reflectivity) of the front facet to the laser beam. The highly-reflective film is disposed on a rear facet of the semiconductor stack structure and is configured to reduce a loss (increase a reflectivity) of the laser beam transmitted to the rear facet. The anti-reflective film and the highly-reflective film respectively have refractive indices greater than 2, and the highly-reflective film has a thickness greater than that of the anti-reflective film.

  • Patent number: 11978340
    Abstract: The present disclosure relates to identifying vehicles using wireless device identifiers. In accordance with aspects of the present disclosure, a system for identifying vehicles in a parking structure includes a camera configured to capture images of an area in the parking structure where the camera captures an image containing one or more vehicle(s), a detector configured to scan for wireless device identifiers in the area, and a processing system including an electronic storage. The processing system is configured to execute instructions to access the image containing the vehicle(s) in the area and access one or more wireless device identifier(s) scanned by the detector in the area, process the image containing the vehicle(s) to extract one or more license plate identifier(s) corresponding to the vehicle(s), and store in the electronic storage at least one record associating the license plate identifier(s) with the wireless device identifier(s).
