Abstract
A sensor for measuring rate of rotation is disclosed which includes a disk resonator, an anchor coupled to the disk resonator and further coupled to a substrate, and an optical waveguide wrapping around at least a portion of the perimeter of the disk resonator, the optical waveguide having an input end and an output end, wherein the disk resonator is configured to expand radially when subject to a rotational input, and wherein said radial expansion is adapted to cause a change in an optical signal passing through the optical waveguide.
