Abstract
An optical transducer is provided that has a flexible transducer member having a set of grooves in one of its major surfaces. Flexure of the transducer member produces a strain pattern that extends across an optical waveguide in the member. This strain pattern has a pitch that will diffract light of a suitable wavelength propagating in the optical waveguide.
