Title: Innovations of Graham Charles Townsend
Introduction
Graham Charles Townsend is a notable inventor based in Menlo Park, CA. He holds a total of 9 patents that showcase his contributions to the field of optical technologies. His work primarily focuses on waveguide-based systems and optoelectronic devices.
Latest Patents
Among his latest patents is a device titled "Waveguide-based transmitters with adjustable lighting." This optical transmission device features a waveguide that includes a transparent medium with mutually-parallel surfaces, allowing light to propagate through internal reflection. The device incorporates a light source that injects coherent light into the waveguide, along with an array of diffractive structures that couple beams of light out through the waveguide's surface. Additionally, it includes tunable optical phase modulators that apply different phase shifts to the beams, modulating the far-field light pattern through interference.
Another significant patent is the "Display with overlaid waveguide." This optoelectronic device consists of a display that emits optical radiation through its front surface. A transparent planar optical waveguide is overlaid on the display, guiding second optical radiation in a different wavelength band. Diffractive structures within the waveguide couple the guided radiation to regions in front of or behind the display, enhancing its functionality.
