Abstract: An eye tracker comprises a light source; a detector; and first and second waveguides. The first waveguide comprises an input coupler for coupling source light into a waveguide path and a first grating for coupling light out of the waveguide path onto an eye. The second waveguide comprises a second grating for coupling light reflected from the eye into a waveguide path and an output coupler for coupling light out of the waveguide path onto the detector. The second grating is optically configured for imaging the eye onto the detector.

Abstract: A contact image sensor having a waveguiding structure for propagating light in a first direction including, in series, a first clad medium, a first core, a switchable grating clad, a second core, and a second clad medium sandwiched by transparent substrates, patterned parallel electrode elements orthogonally traversing the waveguides, a light source, a platen and a detector. Switchable grating regions overlapped by a first voltage-addressed electrode element diffract TIR light from the first core towards the platen. Switchable grating region overlapped by a second voltage-addressed electrode element diffract TIR light reflected from the platen into a TIR path within the second core.

Abstract: An optical waveguide display comprises: a waveguide; a source of light modulated with temporally-varying angularly-distributed information; a fold grating providing a first beam expansion; an input coupler for directing light into total internal reflection paths in a first propagation direction: and an output grating for providing a second beam expansion and extracting light from the waveguide. The input light undergoes at least two diffractions within the fold grating, each diffraction directing light into a unique total internal reflection angular range along a second propagation direction.
