Abstract

Many parameters contribute to the performance of microbend sensors. These include fiber core radius, cladding radius, jacket radius, core and cladding refractive indices, core refracti"e index profile, fiber flexural rigidity, light source wavelength, light source power, spatial bend wavelength, number of bends and bend amplitude. Electromagnetic wave theory predicts that power lost from the core in a microbend is optimum when the fiber's spatial bend frequency equals the difference in propagation constants between the propagating and radiated modes.
