title: Hyperfine aperiodic optical superlattice optimized by iterative domino algorithm for phase-matching engineering.
abstract: We proposed and experimentally demonstrated the iterative domino algorithm to optimize optical superlattice with >10(5) unit blocks to achieve arbitrary target phase-matching power spectrum. This scheme can achieve unprecedented overall conversion efficiency and spectral fidelity with extremely high computation efficiency.
