Optical transmission sheet, optoelectric apparatus, and optical transmission method

摘要

An optical transmission device includes a planar waveguide for transmitting an optical signal, a light emitting unit for inputting a light beam in the planar waveguide, and a setting unit for setting a propagation angle of a light beam transmitted in the planar waveguide. A plurality of light beams with different propagation angles are transmitted in the planar waveguide.
