Abstract:
An optical switching apparatus, comprising:a common waveguide; a first plurality of light deflection elements provided at an input side of said common waveguide, each input side light deflection element including at least one generally prism-shaped element comprising an electro-optic material; a second plurality of light deflection elements provided at an output side of said common waveguide, each output side light deflection element including at least one generally prism-shaped element comprising an electro-optic material; a plurality of lenses provided at the input side of said common waveguide, each of said lenses collimating a light beam which is guided to each of said first plurality of light deflection elements; and a plurality of variably controllable light correction elements at said input side for correcting divergence of the light beam which passes through the first plurality of light deflection elements.
