A singlemode-multimode-singlemode (SMS) fiber structure consists of a short section of
multimode fiber fusion-spliced between two SMS fibers. The mechanism underpinning the …

A wide range of applications such as health, human comfort, agriculture, food processing
and storage, and electronic manufacturing, among others, require fast and accurate …

This work demonstrates that the use of an unconventional optical fiber allows for generating
lossy mode resonances (LMRs), without the need for an external high refractive index (RI) …

This work reports on a novel in-fiber Mach-Zehnder interferometer (MZI) device which is able
to exploit the mode transition phenomena to tailor the sensitivity to external refractive index …

We demonstrated a novel fiber in-line Mach-Zehnder interferometer (MZI) with a large fringe
visibility of up to 17 dB, which was fabricated by misaligned splicing a short section of thin …

We experimentally demonstrate for the first time, to the best of our knowledge, an all-fiber
passively mode-locked laser operation based on the nonlinear multimode interference of …

The mode transition is a phenomenon observed in thin film coated long period fiber gratings
(LPGs) and single-mode multimode single-mode (SMS) fibers for certain values of the …

The high order cladding modes of standard single mode optical fiber appear in quasi-
degenerate pairs corresponding to mostly radially or mostly azimuthally polarized light. In …

This paper presents a complete study on the spectral behavior of a multimode-coreless-
multimode fiber-optic structure, as well as its application as a refractometer and a liquid level …

We proposed and demonstrated a method to improve the birefringence of tilted fiber Bragg
gratings (TFBGs) via high-refractive-index indium tin oxide (ITO) coatings. Firstly, we find the …
