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.

Polymeric optical modulator and waveguiding media

In one embodiment this invention provides a thin film waveguide electrooptic light modulator which consists of (1) a laminated assembly of a waveguiding thin film of an organic polymer which exhibits second order nonlinear optical response, and upper and lower organic polymer blend cladding layers, each of which has a lower index of refraction between about 0.002-0.02 lower than the waveguiding thin film and which exhibits second order nonlinear optical response; and (2) electrodes which are positioned to apply an electric field to the laminated assembly.

Waveguide electrooptic light modulator with low optical loss

In one embodiment this invention provides a polarization-insensitive interferometric waveguide electrooptic modulator device. In a Mach-Zehnder type of waveguide geometry, one of the divergent optical paths has two sets of electrodes, which apply a horizontal electric field and a vertical electric field, respectively, to a nonlinear optically responsive polymeric medium in the optical path. The polymer medium section between each set of electrodes has a noncentrosymmetric molecular orientation parallel to the respective electric fields.
