18 April 2006Novel design of wavelength demultiplexer based on photonic crystal platform
A numerical approach based on the two-dimensional (2D) Finite Difference Time Domain (FDTD) is employed to design, analyse and optimise the wavelength demultiplexer (WDM) based on photonic crystal waveguide couplers. The performance of the WDM is investigated in terms of device length, optical efficiency and losses. Significant improvement on the power efficiency and the wavelength directionality has been achieved by introducing a single defect on the crossing point between two photonic crystal waveguides.
