| description | The effects of 2-D hexagonal-lattice TiO <sub>2</sub> photonic crystal layers on the directional light extraction efficiency of low-scattering (Y <sub>1-x</sub>Ce <sub>x</sub>) <sub>3</sub>Al <sub>5</sub>O <sub>12</sub> (YAG:Ce <sup>3+</sup>) ceramic converters have been investigated. The hexagonal-lattice TiO <sub>2</sub> patterns were fabricated by an electron beam lithography process. The optimized yellow directional light extraction enhancement by a factor of 4.4 is achieved with a 2-D photonic crystal layer having a diameter of 430 nm, a lattice constant of 590 nm, and a height of 350 nm. A 3-D finite-difference time-domain model has also been developed to study the geometric parameters of the photonic crystal layer, yielding results that are consistent with our measured data. |
