Photonic Structures mass 3-D


However, gallium arsenide has to be applied in this case in complex three dimensional structures, through an epitaxial approach which eliminates many of the defects introduced by traditional manufacturing methods, opening a promising way for the creation of photonic structures mass 3-D.
 Another advantage of this new system is the ease of creating on the through different layers. With sudden changes may be possible to vary the materials introduced in the photonic crystal, enabling new applications and uses for these devices. 
 To test their technique, the research group at the University of Illinois at Urbana-Champaign built a 3D photonic crystal LED, the first device of this type for this class of applications. Now, engineers and researchers work to optimize the structure specific applications in mind.
