1. A strain sensor system comprising:

  • 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.
