Assembling of truncated deterministic aperiodic lattices with defects using Weber beams
We introduce an experimental approach to realize truncated 2D deterministic aperiodic photonic structures using the interference of two mutually coherent Weber beams. The optical induction process for generating refractive index modulations in SBN crystal is controlled via various combinations of parabolic beams, with different offsets in both transverse dimensions, orientations, and relative phases, to obtain meta-structures. • A coherent mixture of two Weber beams capable of optical induction of photonic lattice. • Naturally truncated 2D aperiodic lattices realized in one-pass experiment. • Tunable conditions for controllable lattice edge as well as various defect kinds. • Different lattice edge shapes and strengths suitable for surface state investigation. • Generation of distinct aperiodic lattice regions of various shapes and their transition lines.
