Abstract
A waveguide device includes two diffractive optical elements, a waveguide element, and two polarizing units. Each of the diffractive optical elements has a grating configured to diffract light of a wavelength to propagate with a diffraction angle. The waveguide element is configured to guide light propagated from one of the diffractive optical elements to the other of the diffractive optical elements. The polarizing units are at opposite surfaces of the waveguide element and optically coupled between the diffractive optical elements. Each of the polarizing units is configured to reflect light of a first polarization characteristic and transmit light of a second polarization characteristic.
