Reconfigurable holographic lithography for photonic structure fabrication

We present a reconfigurable holographic approach for the fabrication of scalable complex structures of 3D photonic crystals (PCs) as well as photonic quasicrystals (PQCs) by a single step optical induction of refractive index modulation. By means of a spatial light modulator (SLM)-assisted approach we generate these reconfigurable and spatially tunable complex structures. The fabricated nonlinear photonic lattices in SBN:Ce photorefractive medium are analyzed by plane wave guiding, momentum space spectroscopy, and far field diffraction pattern imaging.
