Long-period fiber gratings with variable coupling for real-time sensing applications

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate a long-period grating whose resonance varies in strength but remains fixed in wavelength with either temperature or strain. Using this fiber-grating sensor, we resolved a change of 1 µ of strain or 0.04 °C in temperature. Such sensors require no spectrometer or other frequency-selective components and can operate in real time.
