This is a Phase II SBIR award.  Under Phase I, the technical                    feasibility of producing an optical force sensor using pressure-                induced birefringence has been demonstrated.  This research                     demonstrated that a small force/pressure sensor could be made that has          a large dynamic range, low noise, and low sensitivity to isotropic              environmental changes such as temperature and pressure.  The Phase II           research will include the fabrication of an integrated optical tactile          array made of gallium arsenide/gallium aluminum arsenide.  To                   accomplish this, the sub-elements required for the array will be                modeled, characterized and tested.  These elements include waveguides,          reflectors, wavelength-specific beam splitters, N-way splitters,                lenses, and optical interconnects.  The fabrication will be done using          molecular beam epitaxy.  The optical tactile transducer will be a 3X3           array with sensing sites on 1 mm centers and will be capable of                 resolving forces of less that one milli-Newton.
