Abstract:
A waveguide apparatus, comprises: disposed in at least one layer: an input coupler; a first fold grating; a second fold grating; an output coupler; and a source of light optically coupled to the waveguide providing at least first and second polarizations of the light and at least one wavelength. The input coupler is configured to cause the first polarization light to travel along a first total internal reflection (TIR) path and the second polarization light to travel along a second TIR path.

Claim (Index 18):
A method of propagating light of more than one polarization component comprising the steps of:\n a) providing a waveguide containing an input grating comprising crossed first and second gratings; first and second fold gratings; and an output grating comprising crossed third and fourth gratings; b) coupling a source of light to said waveguide; c) said first grating diffracting a first polarization state of said light into a first waveguide path; d) said first grating diffracting a second polarization state of said light into a second waveguide path; e) said first fold grating diffracting light from said first waveguide path into a third waveguide path to said output grating; f) said second fold grating diffracting light in said second waveguide path into a fourth waveguide path to said output grating; g) said third grating diffracting light in said third waveguide path out of said waveguide; h) said fourth grating diffracting light in said fourth waveguide path out of said waveguide.
