ABSTRACT:
Radiation emitting structures that include an active radiation emitter and a passive photonic crystal structure surrounding the emitter are disclosed. The passive photonic crystal structure is transparent to wavelengths of electromagnetic radiation within the visible region of the electromagnetic spectrum. Also disclosed are incandescent lamps that include such radiation emitting structures.
