Abstract We propose a novel 8-channel wavelength multimode interference MMI demultiplexer in slot waveguide structures that operate at 1530 nm, 1535 nm, 1540 nm, 1545 nm, 1550 nm, 1555 nm, 1560 nm, and 1565 nm. Gallium nitride GaN surrounded by silicon Si was found to be a suitable material for the slot-waveguide structures. The proposed device was designed by seven 1 × 2 MMI couplers, fourteen S-bands, and one input taper. Numerical investigations were carried out on the geometrical parameters using a full vectorial-beam propagation method FV-BPM. Simulation results show that the proposed device can transmit 8-channel that works in the whole C-band 1530–1565 nm with low crosstalk −19.97–−13.77 dB and bandwidth 1.8–3.6 nm. Thus, the device can be very useful in optical networking systems that work on dense wavelength division multiplexing DWDM technology. View Full-Text
