  • Use of waveguides and lenses to improve light communication reception in devices
    Patent number: 11804898
    Abstract: A detection system for light communications comprises a total internal reflection (TIR) waveguide and a light sensor adjacent to the TIR waveguide. The TIR waveguide comprises a TIR structure, a diffusive element, and a waveguide entrance. The TIR structure is configured to internally propagate light associated with optical signaling along the TIR waveguide. The diffusive element is disposed at an internal edge of the TIR structure opposite the light sensor. The diffusive element is configured to disrupt the propagation of the light such that at least some of the light is directed to the light sensor. The waveguide entrance is offset from the diffusive element along the TIR structure and configured to collect the light into the TIR structure.
