Abstract
A light splitting device includes an optical waveguide body and a dispersion grating. The optical waveguide body is configured to transmit incident light to the dispersion grating, the dispersion grating is configured to disperse the incident light transmitted by the optical waveguide body into a plurality of spectral lines, and the optical waveguide body is further configured to change propagation directions of the plurality of spectral lines and to emit the plurality of spectral lines.
