| Abstract: | Based on the expression of Gaussian approximation for the optical waveguide mode field distribution, the functional expression of spectral responsivity of dissymmetrical structure arrayed waveguide grating demultiplexer for its center wavelength is presented,and the relationship between the spectral responsivity and the basis parameters of this demultiplexer is discussed. According to the expression of Gaussian approximation for the spectral distribution of actual channel optical signal, the transmission efficiency of signal channel of dissymmetrical structure arrayed waveguide grating demultiplexer for actual input optical signal is introduced, and the influence of spectral width of the input signal on the transmission efficiency of this demultiplexer is analyzed. |
