Single domain wall effect on parametric processes via Cherenkov-type phase matching
Xuewei Deng, Huaijin Ren, Yuanlin Zheng +1
We report on important influence of single domain wall (DW) of electrically poled ferroelectric crystal on parametric processes via Cherenkov-type phase matching. It shows that the…

Significantly enhanced second order nonlinearity in domain walls of ferroelectrics
Xuewei Deng, Huaijin Ren, Yuanlin Zheng +2
Significantly enhanced second order nonlinearity resulting from local symmetry breaking in domain walls is reported. By this new giant nonlinearity, novel hexagonally, conically an…
