Abstract
One example provides an optical device, comprising a light source configured to output unpolarized light, a polarizing beam splitter configured to split the unpolarized light into light of a first polarization state and light of a second polarization state and a polarization volume grating configured to receive the light of the first polarization state and the light of the second polarization state, and transmit the light of the first polarization state without changing the light of the first polarization state to a different polarization state, and convert the light of the second polarization state to the first polarization state, thereby forming polarized output light.
