Abstract
A photonics sensor including first and second electro-optically active optical waveguides, being substantially parallel. The photonics sensor also includes third and fourth electro-optically active optical waveguides coplanar with the first and second waveguides, the third and fourth waveguides being substantially parallel and intersecting the first and second waveguides at a 90 degree angle. The photonics sensor further includes first, second, third and fourth co-planar and adjacent planar electrodes substantially parallel to the first and second waveguides, the planar electrodes arranged so that an incident electromagnetic signal will impinge upon the planar electrodes. The photonics sensor also includes first, second, third and fourth coupling strips substantially parallel to the planar electrodes, and disposed such that the waveguides lie between the coupling strips and the planar electrodes. Optical signals in the first, second, third and/or fourth waveguides are modulated by a varying voltage potential induced between the planar electrodes and the coupling strips by the incident electromagnetic signal.
