    Abstract: An eyepiece for an augmented reality display system. The eyepiece can include a waveguide substrate. The waveguide substrate can include an input coupler grating (ICG), an orthogonal pupil expander (OPE) grating, a spreader grating, and an exit pupil expander (EPE) grating. The ICG can couple at least one input light beam into at least a first guided light beam that propagates inside the waveguide substrate. The OPE grating can divide the first guided light beam into a plurality of parallel, spaced-apart light beams. The spreader grating can receive the light beams from the OPE grating and spread their distribution. The spreader grating can include diffractive features oriented at approximately 90° to diffractive features of the OPE grating. The EPE grating can re-direct the light beams from the first OPE grating and the first spreader grating such that they exit the waveguide substrate.

    Abstract: Systems and methods for optical power distribution within an integrated device, in a substantially uniform manner, to a large number of sample wells and/or other photonic elements. The integrated device and related instruments and systems may be used to analyze samples in parallel. The integrated device may include a grating coupler configured to receive light from an excitation source and optically couple with multiple waveguides configured to couple with sample wells. Vertical extents of optical modes of individual waveguides may be modulated to adjust confinement of light within the waveguides. This modulation may enable more uniform distribution of excitation light to the sample wells, improve excitation efficiency, and prevent overpower on regions of the integrated device.
