Abstract

We have demonstrated bandwidth control and reshaping of second harmonic (SH) curve in a periodically poled Ti:LiNbO₃ (Ti:PPLN) waveguide ( period=16.6 um) by using a temperature-gradient-control technique and a local-temperature-control technique. We have achieved more than 13 nm second harmonic phase-matching bandwidth and several useful shapes of SH curve such as almost ideal sinc function, and double peaks in a 74 mm long Ti:PPLN waveguide that has pre-chirped SH curve in room temperature.
