title: Fiber-optic acoustic sensors with increased sensitivity by use of composite structures.
abstract: Fiber-optic acoustic sensors having sensitivity nearly 2 orders of magnitude greater than that of sensors using bare fiber are reported. These new devices utilize a composite structure wherein the fiber is embedded in a material of lower elastic modulus that serves to increase the stress, and hence the optical phase shift, in the fiber for a given pressure.
