Abstract
Pressure sensing having 2-D resolution is provided by an array of optical waveguides having wave-guide intersections (e.g., intersecting rows and columns). Pressure induced cross-coupling between intersecting wave-guides is enhanced by including mechanical structures at each intersection that enhance local waveguide bending. For example, such structures can be rigid rings around the wave-guide intersections.
