Paper Abstract

There is an increasing interest in the fabrication of optical parametric devices, pumped by semiconductor laser diodes, for both generation and amplification of tunable coherent radiation. This can be achieved by using waveguiding structures as they permit high optical intensities with modest powers, long interaction lengths and phase-matching using modal dispersion. There have been reports on efficient three wave mixing processes in LiNbO3 waveguides but these require rather high power (>1W). The pump power required can be reduced by either increasing the interaction length or using materials with larger non-linearities. However, to date the maximum phase-matched interaction length has been limited to about 2cm4 in LiNbO3 waveguides due to non-uniformity of the waveguide.
