Abstract

The paper discusses the design and optimisation of the 1310/1550 nm multimode interference demultiplexer using the nanocrystalline diamond waveguide structure deposited on a silica-on-silicon substrate. The demultiplexer is designed by the beam propagation method and the simulation shows that for an optimised structure, the output energy of the fundamental mode is 79.3 % at a wavelength of 1310 nm and 76.3 % at 1550 nm. The designed demultiplexer will be suitable for harsh environmental conditions..
