Abstract:
We report on the observation of a noncollinear difference frequency generation at 1.55μm in an AlGaAs multilayer waveguide. In such three-wave-mixing process, which occurs between a transverse pump beam and two counterpropagating guided modes, the phase matching parameter is the angle of incidence of the pump and the peak efficiency is 3.5×10−6W−1. This innovative device is suitable as a tunable, narrow-bandwidth source of counterpropagating twin photons for quantum information.
