Abstract
We report second-harmonic and sum-frequency generation in GaAs based quantum cascade lasers. Different waveguide designs and active regions were investigated as well as a doping dependence study of the second-order susceptibility in one of the investigated structures is shown. We present farfield measurements which give information about the modal behavior depending on the waveguide design and dimensions. We also demonstrate that grating-coupled surface emission is a highly efficient way to couple out the second-harmonic radiation.
