Abstract

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 ($0.404[c/a]$ at $B_2$ port, $0.389[c/a]$ at $B_3$ port, and $0.394[c/a]$ at $B_4$ 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.
