| Abstract: | For the waveguide grating photocoupler with novel structure,the electric field of the TE guided wave and the TE radiating wave was obtained by solving the Helmholtze equation in the spatial rectangular coordinates.The relations between the coupling coefficient and the different structure parameters of the waveguide and grating were analyzed by using the mode coupling theories.Their corresponding numerical simulation results are given. |
