Abstract
A waveguiding media of polymeric materials is disclosed and claimed. In a preferred embodiment both core and cladding include X.sup.(2) materials poled to a non-centrosymmetric structure. Materials are selected so that the index difference between core and cladding remains relatively constant before and after poling so as to allow for efficient fabrication.
