Here we report a new type of dispersive structure for wavelength multiplexing/demultiplexing, based on a planar 1-D photonic crystal prism. We introduce a computationally efficient technique for simulating this structure. Simulations are carried out to determine the angular dispersion as a function of period, slant angle in the prism area and prism apex angle. The design has been optimized for good performance in a moderate refractive index contrast system (silica and silicon nitride) and promises reduced scattering losses when compared with existing 2-D superprism designs.
