Abstract
A band-gap spectral filter is made of a nanochannel glass structure having a two-dimensional array of parallel dielectric rods arranged in a matrix material. The materials for the dielectric rods and the matrix material are selected so that the difference between the refractive index of the dielectric rods and the refractive index of the matrix material is equal to or less than about 0.5.
