The present disclosure is generally directed to a strain sensor, system and method of fabrication and use that includes an optical fiber, an optical signal generator that transmits an optical signal through the optical fiber, at least two photonic crystal slabs within the optical fiber separated by a first segment of optical fiber, a photo-detector that detects a reflected optical signal from the at least two photonic crystal slabs, and a processor that computes a mechanical strain over the first segment of optical fiber based on the reflected optical signal detected by the photo-detector.

Optical fiber coupled photonic crystal slab strain sensor, system and method of fabrication and use

Optical fiber coupled photonic crystal slab strain sensor system

An optical interrogator system including a broad spectrum light source capable of emitting light having a spectral width spanning at least approximately 20 nm, and at least one optical sensor coupled to the broad spectrum light source by at least one multimode optical fiber, wherein the at least one multimode optical fiber is configured to support a plurality of propagation modes, and a method of using the same are disclosed herein.
