1. An apparatus, comprising:

  • an optical waveguide comprising a material having electro-optic properties, said optical waveguide including a first domain and a second domain, said domains collectively supporting a first optical propagation mode and a second optical propagation mode for optical energy propagating in said waveguide, said modes corresponding to first and second energy distribution patterns; and

    a generator for producing a perturbation in the refractive index of one of said domains relative to the refractive index of the other of said domains of said optical waveguide, said perturbation altering the energy distribution of said optical energy to shift at least a portion of said optical energy from one of said patterns to the other of said patterns.
