✦ Synopsis

Simultaneous wavelength conversion and pulse compression are proposed and demonstrated exploiting cascaded second-order nonlinear processes in periodically domain-inverted LiNbO 3 waveguides. The influences of initial pulse widths and waveguide length on the conversion efficiency and converted pulse compression are theoretically analyzed. Tunable wavelength conversion is performed for the signal pulse with the temporal width of 7.5 ps and repetition rate of 40 GHz. Conversion efficiency of more than Γ€24 dB is obtained for 35-nm conversion span under average signal power of 10 dBm when a CW control wave is adopted.

## Abstract We propose and demonstrate simultaneously inverted and noninverted wavelength conversion of picosecond pulses in periodically poled LiNbO~3~ waveguides. By only use of sum‐frequency generation, inverted wavelength conversion from the signal wavelength to pump wavelength both within the
