(a) Band structure calculated using guided mode expansion for the W0.65 PhC membrane with a BCB substrate and air upper cladding (with air holes). Laterally odd modes are shown in blue, even in red. The thick blue line corresponds to the odd TE-like defect mode. The odd TE-like band edge modes are shaded in cyan. The odd and even TM-like lattice modes are plotted as fainter dotted lines. Low-vg modes are denoted A, B, and C. The light cones of the various cladding materials, air, , and BCB are denoted by progressively darker shading for lower index. (b) Dispersion relation of TE-like modes of the hybrid structure calculated using 3D FDTD for wavevectors around . Both coupled supermodes (solid lines) and uncoupled modes (dashed lines) are represented.
