P‐3.2: Design of waveguide system using one dimension slant grating and two dimension grating

In recent years, augmented reality(AR) technology has gained much attention due to its disruptive and revolutionary nature. Thanks the advanced nano‐imprint lithographic technique, diffractive waveguide based display becomes research hotspot. There are three main types of including one dimension grating, two volume holography. this paper, we proposed that slant grating is used as in‐coupling outcoupling so ratio out‐coupling area could be larger. We analyze orders in K domain. waveguide, uniformity field view moving eyebox (MEB) critical image quality. work, a multi‐objective particle swarm algorithm conducted optimize for better MEB view(FOV). addition, also symmetrical radiate partitions MEB. The design was verified using VirtualLab Fusion last, polarization state system analyzed.
