Efficient frequency conversion over s-c-l-u bands within an electrically pumped chip using ξ 2

Continuous frequency conversion from 1486nm to 1686nm is achieved by utilizing ξ 2 in m-scale AlGaAs chip, where pump is electrically generated within the same cavity where nonlinear conversion takes place. A record high normalized internal conversion efficiency of 342 %W -1 cm -2 is obtained.
