Abstract

A novel Mach-Zehnder interferometer based on a fibre multimode interference structure combined with a long period fibre grating is proposed. The multimode interference is achieved through the use of a multimode fibre section spliced between two single-mode fibres, with a length adjusted to couple a fraction of light into the cladding modes. A LPG placed after the multimode fibre couples light back into the fibre core completing the Mach-Zehnder interferometer. This novel configuration was demonstrated as a bending sensor.
