Spectroscopy was performed along three distinct crystallographic axes of a high refractive index contrast photonic crystal and the spectra were compared with theoretical calculations. Deep dips were observed in the experimental spectra at 2.1 and 3.2 and predicted by calculations. The photonic crystal was prepared through melt-imbibing of selenium into a self-assembled face-centered-cubic colloidal crystal template.
