Web10. jan 2024 · Reflective – uses a molded plastic substrate to guide the light waves and semi-reflective mirror in front of the eye. Images are generated on a micro-display, magnified by a collimating lens, and “the collimated light waves are transmitted to the semi-reflective mirror through the waveguide. Perhaps the simplest optical waveguide is the dielectric slab waveguide, also called a planar waveguide. Owing to their simplicity, slab waveguides are often used as toy models but also find application in on-chip devices like arrayed waveguide gratings and acousto-optic filters and modulators. The slab waveguide consists of three layers of materials with different dielectric constants, exte…

WebUsually, a waveguide contains a region of increased refractive index, compared with the surrounding medium (called cladding). However, guidance is also possible with other physical mechanisms, e.g. by the use of reflections at metallic interfaces, or with photonic crystal structures. Some waveguides also involve plasmonic effects at metals.
