Abstract: A pupil-replicating lightguide includes an in-coupling grating structure, an out-coupling grating structure, and a phase compensation layer. The out-coupling grating structure has a spatially varying parameter such as grating duty cycle or grating thickness for evening out out-coupled distribution of light. The spatially varying out-coupling grating parameter disturbs the phase of the propagating image light. The phase compensation layer has a spatially varying optical thickness that compensates that disturbed phase to planarize an optical phase profile of out-coupled light, thereby improving a modulation transfer function of the pupil-replicating lightguide.

Abstract: An output grating for waveguide of a head-mounted display is configured to suppress the (1, 1) diffraction order of the output grating. The grating has a design of two or more materials having different refractive indices. The design is repeated periodically in a first dimension and repeated periodically in a second dimension, to form a two-dimensional pattern. A refractive index of the two-dimensional pattern is approximated by a two-dimensional Fourier series comprising a first coefficient of order (1, 0), a second coefficient of order (0, 1), and a third coefficient of order (1, 1). The third coefficient is less than half the first coefficient and less than half the second coefficient, such that light from the (1, 1) diffraction order of the grating is suppressed.
