摘要：

We demonstrate difference frequency generation of 4 mu m radiation from 1 to 1.32 mu m pumps in GaAs-based waveguides. Phase matching is obtained by using form birefringence in selectively oxidized AlGaAs/AlAs multilayers, A tunability over 50 cm(-1) around 4 mu m is demonstrated by changing the waveguide temperature and one pump wavelength, A much larger tunability may be achieved by using two tunable sources.
