Image of FIG. 1.
FIG. 1.

Fundamental structure of PC and dispersion surface. (a) Scanning electron microscope (SEM) image of fabricated PC. (b) Part of the dispersion surface calculated using two-dimensional plane-wave expansion method. Dark gray curve and light gray curve denote equifrequency and equi-incident angles, respectively. and are Poynting vectors used for superprism and flat lens, respectively.

FIG. 2.

(Color online) Superprism effect. (a) SEM image of fabricated PC superprism with tapered airhole interface. (b) NFP of refracted light in the superprism. (c) Dispersion of refraction angle observed for three samples with different . Circles denote experimental results and curves theoretical ones calculated in a FDTD simulation.

FIG. 3.

(Color online) DEMUX device and its operation. (a) SEM image of fabricated device. (b) NFP of scattered light at observed from above. (c) NFPs for seven different wavelengths at the end of output waveguides. The top figure shows an optical microscope image of the end of the output waveguides. (d) Demultiplexing action evaluated for six output waveguides.
