Gallium nitride based logpile photonic crystals for visible lighting

Proceedings of SPIE - The International Society for Optical Engineering

Photonic crystals (PC) can fundamentally alter the emission behavior of light sources by suitably modifying the electromagnetic environment around them. Strong modulation of the photonic density of states especially by full threedimensional (3D) bandgap PCs, enables one to completely suppress emission in undesired wavelengths and directions while enhancing desired emission. This property of 3DPC to control spontaneous emission, opens up new regimes of light-matter interaction in particular, energy efficient and high brightness visible lighting. Therefore a 3DPC composed entirely of gallinum nitride (GaN), a key material used in visible light emitting diodes can dramatically impact solid state lighting. The following work demonstrates an all GaN logpile 3DPC with bandgap in the visible fabricated by a template directed epitaxial growth. © 2012 SPIE.
