This paper describes the design, fabrication, and experimental characterization of several photonic integrated components specifically made for a novel retinal projection concept augmented reality applications. The is based on combination optics holography to generate self-focusing image retina. circuit used projector passive fabricated with stoichiometric Si <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> N xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> : single-mode strip waveguides, variable radius bent MMI couplers (Multi-Mode Interference), diffraction grating waveguide crossings. are designed work in visible spectrum at λ = 532 nm. They compact generally show low losses, which two main requirements easily insert wearable glasses enhance quality projector. Our can also find applications variety other fields related spectrum, such as biophotonics, optical phased arrays, light communication more.
