Abstract
The present disclosure provides an optical waveguide structure, including: at least two layers of optical waveguides; a coupling-in grating configured to allow received parallel light beams to enter the optical waveguides, the parallel light beams being propagated in the optical waveguides in a total-reflection manner at a first propagation step; a beam splitting structure configured to allow a first part of light beams to be reflected in such a manner that the first part of light beams are propagated at a second propagation step, and allow a second part of light beams to be transmitted in such a manner that the second part of light beams are propagated at the first propagation step, the second propagation step being different from the first propagation step; and a coupling-out grating configured to extract the light beams propagated in total-reflection manner in the at least two layers of optical waveguides.
