The transmission properties of an off-planar integrated circuit including two wavelength division demultiplexers are designed, simulated, and analyzed in detail by the finite-difference time-domain method. The results show that the wavelength selection for different ports (0.404[𝑐/𝑎]$0.404[c/a]$ at 𝐵2$B_2$ port, 0.389[𝑐/𝑎]$0.389[c/a]$ at 𝐵3$B_3$ port, and 0.394[𝑐/𝑎]$0.394[c/a]$ at 𝐵4$B_4$ port) can be realized by adjusting the parameters. It is especially important that the off-planar integration between two complex devices is also realized. These simulated results give valuable promotions in the all-optical integrated circuit, especially in compact integration.
