Summary: We report on engineered fibers with enhanced optical backscattering that exceeds Rayleigh scattering limits by more than one order of magnitude. We measure attenuation less than 0.5 dB/km from 1,300 to 1,650 nm. By controlling the enhanced b

Continuous measurement of small length scale contortions along an arbitrary path is a highly relevant goal within many branches of engineering and technology. An optical fiber—where the probing light propagates within a confined and shielded region

We demonstrate high spatial resolution fiber shape sensing using one simultaneous measurement of four helically twisted cores, allowing calibration of the fiber spin rate. Our fiber is also shown to have minimal induced mechanical twist.
