Apparatus is provided including an acoustic sensor () having an optical waveguide (). The optical waveguide () includes a waveguide core () having a waveguide core refractive index and a waveguide core photo-elastic coefficient, and an over-cladding layer () coupled to the waveguide core () and including an optically transparent polymer having an over-cladding refractive index and an over-cladding photo-elastic coefficient. The waveguide core refractive index is greater than the over-cladding refractive index, and the over-cladding photo-elastic coefficient is greater than the waveguide core photo-elastic coefficient. Other applications are also described.
