Recent progress on Floquet topological phases has shed new light on time-dependant
quantum systems, among which one-dimensional (1D) Floquet systems have been under …

We model and demonstrate a simple mode selective all-fiber coupler capable of exciting
specific higher order modes in two-and few-mode fibres with high efficiency and purity. The …

We present a comprehensive study of the strain and temperature-sensing characteristics of
single-mode–multimode–single-mode (SMS) structures based on the modal interference of …

Many optical fiber sensors designed to recover quasi-static strain fields in the presence of
significant temperature changes have been reported in recent years. A general theoretical …

The differential modulation of the attenuation bands in a long-period grating is used for
simultaneous sensing of axial strain and temperature. A grating fabricated in a conventional …

A new technique for simultaneous strain and temperature sensing is demonstrated. The
approach employs two different types of photogenerated fiber grating, namely, a fiber Bragg …

We demonstrate that temperature-and strain-insensitive long-period gratings can be
fabricated in conventional optical fibers. The former is employed to measure strain with …

Today a specific attention has been paid to look into the modal characteristics of the high-

Polarimetric and two-mode differential interferometric schemes incorporated in an elliptical-
core fiber are able to resolve strain and temperature simultaneously with resolutions of …

Experimental methods for the practical implementation of few-mode elliptical-core sensors
are described. Techniques for desensitizing the lead-in and lead-out fibers are discussed …
