    Abstract: 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.

    Abstract: A controllable variable optical attenuator for attenuating an optical signal is described herein. The attenuator has an optical waveguide made from similar waveguide core and cladding materials and a coupling layer in close proximity to the waveguide which is configured to provide a difference between the refractive index of the coupling layer in proximity to the waveguide and the effective index of the waveguide. The index of the waveguide can be modified such that if the refractive index of the coupling layer is substantially lower than the effective index of the waveguide, minimal attenuation occurs to the light in the waveguide. Furthermore, if the refractive index of the coupling layer is substantially greater than the effective index of the waveguide, light is coupled into the coupling layer out of the waveguide to attenuate the optical signal. The amount of attenuation varies smoothly between these maximum and minimum values.

    Abstract: In an embodiment, an apparatus is disclosed that includes at least one processor configured to determine a target portion of an eye motion box and to identify a facet of a light-guide optical element that is configured to direct a light beam comprising at least a portion of an image field of view toward the target portion of the eye motion box. The at least one processor is configured to identify a display region of an image generator that is configured to inject the light beam into the light-guide optical element at an angle that, in conjunction with the identified facet, is configured to direct the light beam toward the target portion of the eye motion box. The at least one processor is configured to selectively activate the identified facet and the identified display region to direct the light beam toward the target portion of the eye motion box.
