Description: We rigorously analyze the dispersion function and the curvature of the dispersion surface of a photonic
crystal to explore the fundamental limit of its angular sensitivities. With insight gained from group theory, we
fi nd that symmetry induced degeneracy gives rise to a singular dispersion surface curvature and a nonvanishing
group velocity simultaneously. Near such a singularity, high angular sensitivities can be achieved at low optical
loss. This phenomenon exists generally in most common two-dimensional and three-dimensional photonic
crystal lattices, although it occurs only for certain photonic bands as dictated by symmetry. Platform: |

Description: The dispersion relation and the optical transmittance of a two-dimensional photonic crystal composed of the
hexagonal array of cylindrical air holes fabricated in a dielectric slab were analyzed by group theory and the
numerical calculation based on the fi nite-difference time-domain method. The decay rate of the leaky modes
that exist above the light line ~the dispersion relation in air! in the band diagram was also evaluated, from
which the absence of the coupling between certain internal eigenmodes and the external radiation fi eld was
shown. This phenomenon was related to symmetry mismatching by the group-theoretical argument. -The dispersion relation and the optical transmittance of a two-dimensional photonic crystal composed of thehexagonal array of cylindrical air holes fabricated in a dielectric slab were analyzed by group theory and thenumerical calculation based on the Platform: |

Description: We have used phase-sensitive ultrashort-pulse interferometry to study the modifi cation of optical
pulse propagation near the photonic band edges in colloidal crystals consisting of polystyrene spheres in
water. A strong suppression of the group velocity is found at frequencies near the L gap of the fcc lat-
tice. The group velocity dispersion diverges at the band edges and shows branches of both normal dis-
persion and anomalous dispersion, which can be interpreted as large changes in the effective mass, both
positive and negative. We obtain excellent agreement with the dynamical diffraction theory. Platform: |
