Claim 0:
1. A method of operating an optical channel comprising:
directing light through an entrance pupil of an optical channel body, the light being directed in a direction perpendicular to a back surface of the optical channel body, wherein the light experiences angularly varying total internal reflection between a front surface and the back surface, wherein the front surface and the back surface are non-parallel, such that the light that exits the optical channel body perpendicular to an exit pupil is at a wavelength shifted from the center wavelength, wherein a wedge overlay adjacent to the front surface of the optical channel body opposite the entrance pupil defines non-parallel front and back overlay surfaces and at least some of the angularly varying total internal reflection between the front surface and the back surface are between the front overlay surface of the wedge overlay and the back surface of the optical channel body.
