Abstract

We propose a silicon-on-insulator (SOI) photonic crystal waveguide within a hexagonal lattice of elliptical air holes for slow light propagation with group velocity in the range 0.0028c to 0.044c and ultra-flattened group velocity dispersion (GVD). The proposed structure is also investigated for its application as an optical buffer with a large value of normalized delay bandwidth product (DBP), equal to 0.778. Furthermore it is shown that the proposed structure can also be used for time or wavelength-division demultiplexing to separate two telecom wavelengths, 1.31 mu m and 1.55 mu m, on a useful time-scale and with minimal distortion.
