Abstract： This work introduces the first domestically developed 3D visualization module for optical waveguide design and simulation based on ray-field tracing. Using this module， we engineers a two-dimensional exit-pupil-expansion diffractive waveguide， demonstrating a systematic design workflow， which integrates k domain analysis， automated layout generation of grating regions within the optical waveguide， waveguide optimization， and ray-field tracing simulations， establishing a cohesive methodology for device development. The module extends beyond single-waveguide simulations to system-level analyses of near-eye displays， incorporating micro-dislplays， micro-projectors，and human eye models. By bridging microscopic and macroscopic scales， it enables holistic performance evaluation of AR optical systems， highlighting its capabilities and technical advantages.This module provides a robust and efficient platform for domestic optical engineers to advance optical waveguide design and simulation， thereby accelerating the industrialization and technological progression of AR optics in China.
