Abstract

An input coupler component, optical display system and electronics apparatus are disclosed. The input coupler component comprises: an input polarization volume grating, which is disposed to deflect an input polarized electromagnetic wave into a waveguide in a total internal reflection manner; and an input polarization management layer, which adjusts the polarization of the deflected electromagnetic wave to a polarization state different from that of electromagnetic wave to be deflected by the input polarization volume grating.
