Scanning electron microscope image of the PhC.
(Color) Measured angular-resolved spectrum. Inset: Excitation geometry.
(Color) (a) Measured band structure of the PhC (log scale). (b) Measured and theoretical (red dots) band structure. (c) Measured (blue) and theoretical (red) emission along a band [indicated by an arrow on figure (b)]. (d) Zoom on an anticrossing.
(a) Two-dimensional band structure of a photonic crystal in the direction. (b) Corresponding band structure in a multimode waveguide: mode gives rise to two PhC bands, and .
