increasing interest and developed into various sensors used in many practical applications …

Background The tip of an optical fiber has been considered an attractive platform in Biology.
The simple cleaved end of an optical fiber can be machined, patterned and/or …

The multimode interference (MMI) concept has been comprehensively studied in the past
few years in order to develop new optical devices [1]. Typically, the MMI-based fiber device …

A novel all-fiber sensor based on cascaded singlemode-no-core-singlemode (SNS) and
siglemode-multimode-singlemode (SMS) fiber structure is proposed and investigated …

Tapering single-mode-multimode-single-mode structures to enhance sensitivity is proposed
and experimentally demonstrated. 50-mm-long coreless multimode fiber sections are …

A temperature sensor based on a multimode–singlemode–multimode (MSM) fiber structure
has been proposed and experimentally demonstrated. By utilizing the interference between …

We implement the strain and temperature sensors based on multimode interference in
perfluorinated (PF) graded-index (GI) plastic optical fibers, and investigate their sensing …

Optical fiber sensors have been studied, developed, and already used in the industry for
more than 50 years due to their multiplexing capabilities, lightweight design, compact form …

A single-mode fiber (SMF) sensor based on core-offset inter-modal interferometer is
demonstrated. Compared with the sensing head with the two core-offset joints, the improved …

Singlemode-multimode-singlemode fiber structures (SMS) based on distinct sections of a
pure silica multimode fiber (coreless-MMF) with diameters of 125 and 55 μm, were reported …
