Bio-inspired spatially variant photonic crystals for self-collimation and beam-steering applications in the near-infrared spectrum

Abstract The self-collimation of light through Photonic Crystals (PCs) due to their optical properties and through a special geometric structure offers a new form of beam steering with highly optical control capabilities for a range of different applications. The objective of this work is to underst...
