18. A method of illumination, the method comprising:
-
emitting light into a bottom waveguide; propagating the light to an edge of the bottom waveguide; reflecting the light at the edge into a top waveguide disposed over the bottom waveguide; and emitting the light from a top surface of the top waveguide, an intensity of the emitted light being substantially uniform over the top surface. - View Dependent Claims (19, 20)
