Abstract
A semiconductor light emitting device for emission of light having a predetermined bandwidth in a primary direction of emission includes a light generating region for the generation of light; and a 1-dimensional photonic crystal structure having a photonic bandgap covering at least a segment of said bandwidth. The 1-dimensional photonic crystal structure is located such that upon incident of light from the light generating region, light having a wavelength within the bandgap of the 1-dimensional photonic crystal structure is reflected in the primary direction of emission.
