Abstract: A luminescent photonic structure that comprises a luminescent material that when excited by an excitation light having a wavelength within an excitation wavelength spectrum of the luminescent material emits luminescent light having a luminescence wavelength spectrum. The luminescent photonic structure comprises a photonic crystal disposed between two other photonic crystals. The photonic crystal has a photonic lattice period within one of the luminescence wavelength spectrum and the excitation wavelength spectrum. The two other photonic crystals each have a photonic lattice period within the other of the luminescence wavelength spectrum and the excitation wavelength spectrum for reflecting one of excitation light and luminescent light propagating within the photonic crystal.
