Abstract

The strong wavelength dependence of microbending losses in single-mode fibers is utilized in wavelength referencing for fluctuation-free microbend sensors. Through fiber size and microbend periodicity, optimization of the wavelength dependence can be increased dramatically. The reference and signal wavelengths can be provided through the spectrum of a light-emitting diode.
