Latest Patents

One of Grief's notable patents is the "Waveguide concentrator for light source." This invention involves a light source or projector designed for near-eye displays. The system includes a light source subassembly that is optically coupled to a waveguide concentrator. The subassembly features several semiconductor chips, each hosting an array of emitters such as superluminescent light-emitting diodes. These chips are arranged side-by-side, with their emitting sides coupled to the waveguide concentrator. This design allows for a tight array of output light ports on a common output plane. The output diverging beams from these ports are then coupled to a collimator, which collimates the beams and directs them to an angular scanner. This setup enables the scanning of collimated light beams across the display's field of view.
