Abstract
An optical signal deflector comprising an optical signal waveguide formed of plural layers of optically non-linear semiconductor material, apparatus for launching a first optical signal in the waveguide in a first direction which is parallel to the layers, apparatus for applying a second optical signal to the waveguide in a second direction parallel to the layers but at an angle to the first direction, the thickness and indexes of refraction of the layers being predetermined to cause non-linear field contributions of the signals to add in phase in the far field, whereby a third optical signal is obtained having an angle of emission which is the three dimensional vector addition, at a harmonic sum frequency, of the first and second signals.
