    摘要： Methods of attenuating, delaying the phase, and otherwise controlling an optical signal propagating along a waveguide are provided. According to one method, a variable optical attenuator structure is provided comprising a waveguide core, a cladding, an electrooptic polymer, and a set of control electrodes. The core, the cladding, and the electrooptic polymer are configured such that an increase in the index of refraction of the polymer causes a substantial portion of an optical signal propagating along the waveguide core to couple into a relatively high index region of the electrooptic polymer above the waveguide core, so as to inhibit return of the coupled signal to the waveguide core. Another embodiment of the present invention introduces a phase delay in the coupled optical signal and permits return of the coupled signal to the waveguide core. An additional embodiment contemplates the use of a ridge waveguide structure to enable control of the optical signal. Additional embodiments are disclosed and claimed.

    摘要： Waveguide devices and schemes for fabricating waveguide devices useful in applications requiring modulation, attenuation, polarization control, and switching of optical signals are provided. In accordance with one embodiment of the present invention, a method of fabricating an integrated optical device is provided. The method comprises the acts of: (i) providing a support wafer defining an electrode support surface; (ii) forming an electrode pattern over the electrode support surface of the support wafer; (iii) forming a non-polymeric buffer layer on at least a portion of the electrode pattern and over at least a portion of the support wafer; (iv) forming a waveguide core material layer over the non-polymeric silica-based buffer layer; (v) removing portions of the core material layer to define a waveguide core; and (vi) positioning a cladding material in optical communication with the waveguide core such that the buffer layer, the cladding material, and the waveguide core define an optically-clad waveguide core.
