We propose a two-dimensional exit pupil expansion (2D-EPE) design of a diffractive
waveguide (DW) based on polarization volume grating (PVG). The designed waveguide …

Scattered light from outdoor LED sources is a major contributor to blue-spectrum light
pollution which negatively impacts ecology and public health. Volume holographic diffractive …

Holographic optical waveguide is the most practical waveguide coupling technology for
head-mounted augmented reality displays (HMD-AR) due to its advantages of small size …

We report on the realization of Distributed Feedback (DFB) lasing by a high-resolution
reflection grating integrated in a Photomobile Polymer (PMP) film. The grating is recorded in …

We proposed a single-layer color echelle grating combined optical waveguide structure for
