Due to the utilization of on-chip compact diffractive cells (slab waveguides), both the footprint and power consumption of the proposed architecture is reduced from quadratic scaling in the. Our success has only been made possible with the launch of concurrent innovative solutions by our partners and a stellar example is the Dispelix LED waveguide. Two-dimensional (2D) exit pupil expansion, as a key technology for near-to-eye display, can be realized by using diffractive gratings. The eye box size of the WaveOptics 40-degree FOV module can reach around 19 by 15 mm2, largest among all similar products in the market. Waveguide displays are made using the same technology that allows a unidirectional wave of light to be guided down a fiber optic. Led by the world's most sought-after experts in optics, photonics and manufacturing, Dispelix is headquartered in the technology hub of Espoo, Finland with field offices throughout the United States, China and Taiwan.
