Prospects for unification under 4-dimensional optics

4-dimensional optics is here introduced axiomatically as the space that supports a Universal wave equation which is applied to the postulated Higgs field. Self-guiding of this field is shown to produce all the modes necessary to provide explanations for the known elementary particles. Forces are shown to appear as evanescent fields due to waveguiding of the Higgs field, which provide coupling between waveguides corresponding to different particles. Carrier particles are also discussed and shown to correspond to waveguided modes existing in 3-dimensional space.
