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