Fiber In-Line Mach-Zehnder Interferometer Based on a Pair of Optical Fiber Diffraction Gratings

Optical fiber in-line Mach-Zehnder interferometer for strain and refractive index sensing is proposed based on a pair of multi-column diffraction gratings. In the device operation, part of the light traveling in the fiber core diffracted to the cladding region through the first set of multi-column d...
