Abstract
A colored light source apparatus is provided. The apparatus includes light sources corresponding to active regions defined by defects in a photonic crystal structure, wherein the photonic crystal structure is based on periodic structures. The apparatus also includes a waveguide, a first electrode, and a second electrode. Varying electrical properties between the first and second electrodes stimulates radiation production in the active regions, wherein the radiation is at least partially coupled to and guided by the waveguide.
