Abstract
Tunable wavelength conversion between picosecond pulses is demonstrated by exploiting cascaded secondorder nonlinearity in periodically poled LiNbO3 waveguides when the pump pulse with 40-GHz repetition rate and 7.5-ps pulse width is adopted. No external continuous-wave input is required in the proposed wavelength converter. The converted signal wavelength can be tuned from 1519 to 1562.6 nm as the lasing wavelength is changed from 1534.5 to 1572.1 nm.
