FIELD: physics.
SUBSTANCE: waveguide has a bottom part with a conical cut of height h<H, where H is thickness of the waveguide. Input radiation propagates from the conical cut to edges of the waveguide. The disclosed waveguide also has a second conical cut on which a mirror coating is applied, coaxial to the conical cut in the bottom part.
EFFECT: device enables uniform radial propagation of light entering the planar waveguide with maximum efficiency.
