A Mach-Zehnder interferometric optical fiber sensor is proposed and demonstrated for strain
and temperature discrimination. The sensor is fabricated by connecting a standard single …

In this paper, we present the fabrication of a new fiber-optic pH sensor based on the macro-
bending loss properties in a droplet-shaped single-mode fiber (SMF) bending structure for …

A novel π-phase-shifted (PS) long-period fiber-grating (LPFG) sensor operating near the
phase-matching turning point (PMTP) was proposed. The PS-LPFG sensor can …

A fiber optic Mach–Zehnder interferometer (MZI) sensor based on a semi-open cavity
