Reconfigurable Geometric Phase Matching by Multilayered Nonlinear Thin-Film Crystals
Danielle Ben-Haim, Mai Tal, Xiaoxi Xu +1
Phase matching is essential for efficient energy transfer in nonlinear wave-mixing processes. Traditional methods, such as birefringent and quasi-phase matching, have remained conc…
