Abstract : This investigation relates to a pressure insensitive optical fiber waveguide for use as leads to and reference fibers in instrumentation that is to be desensitized to environmental cyclic or varying acoustic pressures (usually hydrostatic). More specifically, the invention provides for coating an optical fiber (core and cladding) of low bulk modulus with a substrate of high bulk modulus of selected thickness for a resultant no phase change in light passing through the optical core due to the acoustic pressure changes. The substrate may be further jacketed by combinations of relatively low bulk modulus coatings to protect the optical fiber from mechanical or structural damage. (Author)
