A non-radiative dielectric waveguide is a type of optical waveguide that confines light through total internal reflection without the emission of radiative energy. In these waveguides, light travels through a dielectric (non-metallic) material, typically glass or a polymer, and is confined to the waveguide structure rather than radiating out into the surrounding medium.
