Abstract
Photonic Crystals (PCs) are a distinct class of dielectrics which facilitate the control over both propagation of light and the inhibition of spontaneous emission of light from atoms and molecules. The successful fabrication of such structures represents a great leap towards an integrated photonic.
We show that complete three-dimensional photonic band, gaps (PBGs), spanning roughly 10% of the gap center frequency are attainable by incomplete infiltration of an opal with silicon. In addition, we demonstrate that when an optically birefringent nematic liquid crystal is infiltrated into the void regions of an inverse opal PC, the resulting composite material exhibits a completely tunable PBG. Measurements on analogous two-dimensional PCs show that the photonic band edge may be shifted by more than 100 nm.
