Photoluminescence in Doped 1-D Photonic Crystals

Interference effects inside a photonic crystals provide mechanisms for the precise control of light both within and outside of the photonic crystal. In particular the emission direction, spectrum, intensity, and dynamics can be affected by the band structure. We will study these photoluminescence properties in one-dimensional polymeric photonic crystals containing photoluminescent organic dopants, which are fabricated either by a co-extrusion/multiplication process or by stacking of individual layers. We will also be investigating applications of such structures in surface emitting distributed feedback lasers and as color and emission control elements for efficient solid state lighting.
