Embedding defect sites into hexagonal nondiffracting wave fields
Andreas Kelberer, Martin Boguslawski, Patrick Rose +1
We present a highly purposive technique to optically induce periodic photonic lattices enriched with a negative defect site by using a properly designed nondiffracting beam. As the…

Multiplexing complex two-dimensional photonic superlattices
Martin Boguslawski, Andreas Kelberer, Patrick Rose +1
We introduce a universal method to optically induce multiperiodic photonic complex superstructures bearing two-dimensional (2D) refractive index modulations over several centimeter…
