1. A method of operating an eyepiece waveguide, the method comprising:
directing light from a projector to impinge on an incoupling grating (ICG);
diffracting a first fraction of the light from the projector into a first portion of the eyepiece waveguide, propagating the first fraction of the light into a second portion of the eyepiece waveguide, and diffracting the first fraction of the light out of the eyepiece waveguide; and
diffracting a second fraction of the light from the projector into the second portion of the eyepiece waveguide, propagating the second fraction of the light into the first portion of the eyepiece waveguide, and diffracting the second fraction out of the eyepiece waveguide.
