Abstract: An electro-optic device 200 comprising a substrate in which first and second waveguides 202, 203 are formed. The device also comprises first and second electrodes 204, 205 comprising an optically transparent conductive material and including primary portions 204a, 205a overlying the first and second waveguides 202, 203 for electrically biasing the first and second waveguides. The device is configured such that one of the first and second electrodes includes one other portion 204b, 205b arranged alongside the primary portion 204a, 205a of the other of the first and second electrodes. This arrangement improves the electro-optic efficiency of the device without the need for a buffer layer in the electrodes.

Abstract: To enable analysis of a signal associated with surveying a subterranean structure, a processing system receives a time series of the signal associated with surveying the subterranean structure. A visualization of the time series is generated, where the visualization is a time-based representation of a characteristic of the signal. The visualization enables a determination of whether undesirable variations occur with the signal over time.

Abstract: A computing system, method, and computer program product display a plurality of metric values by forming a plurality of cells within a two-dimensional array and generating and displaying, within the plurality of cells, an indication of mutual importance for a set of metric values associated with two entities. The two entities are within one business entity or represent two business entities. The indication of mutual importance is selected from a fixed set of values of relative importance and indicated by one of a set of colors, a set of grey-scale tones, a set of backgrounds, a set of patterns, and a set of cell border styles. The method further identifies at least two metrics values in conflict, creates a diagram wherein conflicting metrics values are arranged in a circular manner, and indicates a relationship between conflicting metric values as a line with a steering direction indicated by an arrowhead.

Abstract: An electro-optical device capable of modulating the amplitude or phase of an optical output in response to an electrical data or control signal, or of switching it, has reduced frequency-dependence and a better combination of operating voltage and bandwidth. It comprises a body of electro-optically active material, waveguides for passing light through the body, and electrodes for applying an electric field with a frequency in the microwave region to the body, and its transverse geometry is such as to maintain adequate phase velocity matching between optical and microwave frequencies. There is a discontinuity in either the body or at least one of the electrodes such that the direction of the electro-optic effect is reversed for a portion of the length of the device at or near its downstream end.
