[Special Effects] 1c DL : 0: 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.

[Other] 2e DL : 0: 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.
