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 …

The aim of this paper is to provide a comprehensive review of mode-division and spatial-
division optical fiber sensors, mainly encompassing interferometers and advanced fiber …

We review fiber-based multimode interference (MMI) devices with a particular focus on
optical fiber-based sensing applications. The present review complements a recently …

Respiration rate (RR) is an important information related to human physiological health. A
